Core bugs

Name Status Patch Description Additional info
C341-1 Moot Monsters affected by stinking cloud always get angry at the hero even if the hero did not create the cloud. The bug is actually mostly fixed in NetHack 3.4.3, with one minor exception; the bug will still occur if loading a bones file from an older game in the 3.4 series.
C341-4 Moot opthelp does not list use_inverse Entire opthelp will be scrapped and replaced by something less broken
C341-5 Confirmed When you see your pet move, the pet may be referred to as "it". See Bugs_in_NetHack_3.4.3/Reports#C341-5
C341-7 Unknown Skilled or expert caster of fireball/cone of cold can't target a monster known only by infravision or ESP. Fixed by Grunt.
C341-10 Unknown Fruit names ending in "us" are incorrectly considered plural. Clearly singular -us words that someone might conceivably use as a slime-mold name include cactus, lotus, fetus, octopus, platypus, torus, walrus; clearly plural ones include caribous, kudzus, marabous, menus, zebus; ones that can be either include asparagus, acanthus; adjectives include citrus, nutritious. Asparagus (the only one that's widely considered a food in the English-speaking world) and lotus (due to famously being eaten in the Odyssey) are the only such words that are even vaguely likely to turn up (unless someone is being deliberately over-the-top silly, in which case they deserve whatever weird message the game gives them).
C341-18 Unknown ki-rins and couatls can wear (and may have) armor. Shields, boots, gloves, and (non-metallic for ki-rin) helmets. Fixed by Grunt.
C342-12 Help There are a number of places that misuse "your". What are these places?
C342-13 Unknown Hangup can cause loss of objects being moved internally. What are the circumstances in which this will occur?
C342-16 Unknown If you self-genocide while polymorphed, the death message makes no sense. "You return to [racial] form. DYWYPI?" GruntHack changes this to "As you return to [racial] form, you die."
C342-19 Unknown Things that can kill you in the future (like stoning) can cause messages to show up out of order. "You are a statue. Your skin begins to peel away." Fixed in GruntHack.
C342-22 Unknown Monsters can hide under cockatrice corpses without getting stoned. Also: "You sit on the cockatrice corpse. It is not very comfortable." GruntHack contains a fix for this.
C342-31 Help You can get a message telling you a monster wields a weapon it already was wielding. It's not clear how to reproduce this. There's a FIXME at line 616 in weapon.c that could potentially be (indirectly) related.
C342-36 Unknown If unable to see yourself while invisible and you are bestowed a spellbook, it doesn't show up on the display.
C342-46 Unknown Cleric cast lightning doesn't blind as other lightning does. Refers to the monster cleric spell, CLC_LIGHTNING. GruntHack fixes this.
C342-50 Unknown If you're hiding on the ceiling and try to #sit, you automatically unhide. #sit, #monster, #sit: "You sit on the helm of brilliance. It's not very comfortable... You are already hiding."
C342-51 Unknown The game thinks trappers hide on the ceiling. In D&D, they apparently hide on the floor. Turns up in two known places: dislodging a trapper with a drum of earthquake, and ambushing a monster while in trapper form. Fixed by Grunt.
C342-54 Fix available GruntHack Statues of unique monsters in bones files are not handled correctly. Unfortunately GruntHack fix depends on extension of structures introduced previously in this variant. Multiple unique monster problem also may be caused by corpses. If the unique monster in question doesn't normally spawn on that level, and was rather brought there from some other level (in the other game), zapping stone to flesh at it causes a segfault.
C343-1 Fixed NitroHack At a pit the game can give messages with poor grammar. Levitate over pit, while blinded, drop something: "The food rations tumble into the pit.", "You hear The amulet of reflection tumbles downwards."
C343-2 Fix available [1] Wielded silver arrows don't cause silver damage on some silver-haters.
C343-3 Unknown In the ranger quest, monsters can end up off the map to the left. The special level loader introduces a two column gap to the left of the main maze area; Jonadab thinks the monsters get generated back there. GruntHack fixes this by removing the two column gap in the special level loader.
C343-4 Fix available GruntHack On the Rogue level, tunnelling through rock doesn't leave a passage.
C343-5 Unknown In wizard mode, level teleport in the endgame can cause a crash if confused. Fixed by Grunt.
C343-6 Fix available [2] You can #sit on an object at the bottom of a pit that you are not in.
C343-7 Fix available [3] When a steed pushes a boulder into a pool, the message misuses "you".
C343-8 Fixed UnNetHack Plural of Nazgul is Nazgul - not Nazguls.
C343-9 Unknown Trap messages referring to a named steed when hallucinating are poorly worded. If riding at the time, e.g. "You lead poor fire giant into a pit!". Fixed in GruntHack, though by a more complicated means than necessary for vanilla / NH4.
C343-10 Unknown If there is a food in a pit, you have to enter the pit to pick it up but not to eat it. Fixed in GruntHack.
C343-11 Unknown If you ask for help ('?') at a "what direction" prompt, you don't get to enter a direction afterward if the cmdassist option is set.
C343-12 Fixed UnNetHack You can't use '>' to enter a pit.
C343-13 Unknown On polymorph, you can get the message "It turns into it". According to Grunt, this happens in vanilla if an invisible purple worm swallows a shapechanger. Confirmed in NH4 with an invisible pet w and a chameleon.
C343-14 Fixed GruntHack The initial and any tombstone message resulting from eating an identified artifact is gramatically incorrect.
C343-15 Fix available [4] You can get a message that an invisible monster looks much better.
C343-16 Fixed UnNetHack Player polymorphed as a xorn can't pick up items in pits. You have to fall into a pit, which xorns can't.
C343-17 Fixed UnNetHackPlus+[5] After polymorphing into a xorn and returning to human form, player can be stuck in a pit that isn't there. After polymorphing into any non-phasing monster, you are reliably stuck in a nonexistant pit.
C343-18 Unknown Scaring a mimicing mimic gives an incorrect "turns to flee" message. Immobile monsters can have the "flee" status, but will not move away from you. Fixed by Alex Smith.
C343-19 Fixed Bilious #340 Dipping acid in a fountain may not destroy the acid.
C343-20 Unknown When dying immediately on entering a level, the map may show you dying on the previous level. Notes: Can be reproduced by falling down a trap door with a wielded cockatrice corpse; bones will be saved on the destination level.
C343-21 Unknown Pets can be pulled through closed doors with a leash.
C343-22 Not a bug You can untrap a monster in a pit while levitating. Source code comment ("This works when levitating too -- consistent with the ability to hit monsters while levitating.")
C343-23 Fix available GruntHack Dungeon collapses after vault guard fails to lead you out. Instructions to reproduce bug
C343-24 Fixed UnNetHackPlus Documented default for option "null" is "off"; default is actually "on".
C343-25 Unknown You can trip over a cockatrice corpse safely. Wear gauntlets of fumbling and walk around among cockatrice corpses. "You see here a cockatrice corpse. You trip over it. You make a lot of noise!" Fixed in GruntHack, where tripping is unsafe if not wearing boots.
C343-26 Unknown A frozen swamp may be called a moat. Go to Juiblex's Swamp and start zapping around with a wand of cold. "The moat is bridged with ice! You hear a cracking sound." Fixed, along with several related misuses of "moat", in GruntHack by greater use of waterbody_name.
C343-27 Fix available [6] Kicked objects do not slide properly on air or water levels.
C343-28 Fix available [7] There are several places that can't tell the diffence between a "hat" and a "helmet." There are some objects which are referred to in their descriptions as "hats" (elven leather helm -> "hat", dwarvish iron helm -> "hard hat", cornuthaum and dunce cap -> "conical hat"; one could argue that this applies to fedoras as well despite not having a separate description, as it's not a helmet). Several places in the code ("Fortunately, you are wearing a hard helmet"; "Your helmet blocks the attack to your head") always refer to the object in your armor slot as a helmet, even when it can't properly be described as a helmet (such as having a fedora block a mind flayer attack).
C343-29 Unknown When taking things out of a bag of holding, messages may say "lifting" instead of "removing." This happens when you get the confirmation asking if you want to continue (because your encumbrance level would increase and you are over your threshold). Fixed in GruntHack.
C343-30 Fixed GruntHack Cursed scroll of destroy armor on cursed armor doesn't always interact correctly. You can make the stats gain from putting on an enchanted helm of brilliance or gloves of dexterity permanent by cursing the armor and reading cursed destroy armor.
C343-31 Unknown If you hit a cockatrice with a weapon that breaks, you can be stoned. Reproduced by wielding a boomerang in melee combat with negative luck. Fixed in GruntHack.
C343-32 Unknown When blind and levitating, the hero can still discover stairs. Use the go down command. "You are floating high above the stairs." Fixed by Grunt
C343-33 Fix available [8]partial fix Sometimes a monster may remain hidden under a corpse that has rotted away.
C343-34 Fix available GruntHack Mimics on the rogue level may try to mimic a closed door.
C343-35 Unknown Polymorphed or shapechanged monsters may get the wrong number of hit points. On polymorph, the ratio HP / max HP is preserved, perhaps this bug refers to rounding errors.
C343-36 Fix available GruntHack Weight of corpses on special levels may not be calculated correctly. This also goes for statues, e.g. the Oracle centaur statues.
C343-37 Not a bug Mimics may mimic a boulder over a pit or hole.
C343-38 Unknown Dismounting and kicking a monster that jumps may result in landing on the wrong side of a wall. Kicking a monster makes them mnexto() you, then tries to flavour the resulting movement. In very confined spaces, mnexto() may not be able to find a space next to you after all. This applies to many monsters with speed >= 12 with a chance of 1/3 or 1/4 depending on how well you kicked, and the bug occurs whether it’s flavoured as “jumps” or “slides” or “floats” or whatever. (A subsidiary bug here: it can also be flavoured as “teleports”, yet trigger on a no-tele level.) Fixed by Grunt.
C343-39 Fix available GruntHack Restoring a game where the character is wielding Sting may result in temporary display errors during the restore process.
C343-40 Fix available GruntHack Monster thrusting one of multiple wielded daggers gives misleading message. The interface isn’t clear that wielding 6 daggers, or whatever, nevertheless means that you only attack with one. Also "[09:01] <Dentarthur> The soldier wields 14 spears!" (from #nethack)
C343-41 Fix available [9] A rolling boulder falling into a pit you can't see only makes a sound if the hero is blind.
C343-42 Fix available GruntHack If a fire trap melts ice, it may trigger twice in the same turn. "Reproduced via polyself into a red dragon." (Bugs in NetHack 4) - whatever it may mean.
C343-43 Unknown An invisible troll that revives may be shown until it moves.
C343-44 Fix available GruntHack Shopkeepers, doors, and traps interact oddly. For example, if you break a wand of digging on the entrance square, the shopkeeper will usually remove only some of the pits.
C343-45 Fix available [10] Dropping the corpse of a unique monster without a personal name down the stairs gives a badly formed response.
C343-46 Help Breaking up a boulder or statue can result in pieces that are described incorrectly. Described where? The rocks that result don't seem to be the problem.
C343-47 Fix available [11] Monster and hero have different odds to err when throwing a greased weapon. Players throwing greased weapons have the same chance of them misfiring as if the object is cursed; monsters throwing projectiles suffer no penalty for throwing greased weapons at all.
C343-48 Unknown Killing your pet doesn't get you any experience when it should. Vanilla: This might refer to the fact you won't break pacifist conduct if you branchport into an already-full level - pets and followers simply disappear. The pacifist page has a few more "safe" ways to kill things.
C343-49 Fix available GruntHack The boulder does not show up in a bones file caused by death by rolling boulder. Fixed in GruntHack by allowing the boulder to finish moving before dealing damage to the player (this leaves the trap ready to snare whoever next comes across the bones). Possible alternative solution: place the boulder where the player is before triggering the damage in the current code flow, leaving the boulder on top of the corpse.
C343-50 Fix available AceHack A sleeping steed may answer a #chat. dochat (sounds.c) checks to see if you’re talking to a steed before it checks to see if the monster is asleep.
C343-51 Unknown Luck's effect on random events isn't always as intended. Several beneficial events are most likely with Luck=7, not maximum Luck. See rnl for details.
C343-52 Fixed unnethack Worn or wielded objects destroyed by dipping into lit potions of oil are not handled properly; this can result in odd game behavior. For example, if you dip your (worn) thoroughly burned robe into lit oil until it's destroyed and then try to wear another cloak you can't, because you're already wearing the robe, even though you aren't.
C343-53 Unknown If a shopkeeper is trapped adjacent to the door, the game may get confused and issue impossible or panic messages. TJR says break a wand of digging while standing next to the shopkeeper.
C343-54 Confirmed [12] "Ulch" cannibalism message grammar is poor. Eating a zombie of your race: "Ulch - that meat was tainted cannibal! You feel deathly sick."
C343-55 Fixed UnNetHack "Ulch" messages have inconsistent capitalization.
C343-56 Fix available [13] Gas spores can't attack while hero is praying. A spurious "starts to attack you, but pulls back" message is displayed, even though gas spores have only passive attacks.
C343-57 Fixed UnNetHackPlus #enhance command descriptions in Guidebook and game do not match.
C343-58 Fixed UnNetHackPlus #conduct command description grammar is poor
C343-59 Confirmed [14] (real change at the bottom, after extern mess) Engulfer stoned swallowing hero polymorphed to cockatrice causes incorrect screen display. If hero has ball & chain, game can panic. Reproduced with a hostile trapper. The t remained on the display in its original location adjacent to the polyselfed hero for several turns, even though there was a statue of a trapper on the tile with the hero.
C343-60 Unknown Several messages delivered when hero's fingers are slippery have poor grammar. Which messages?
C343-61 Unknown Using a WIZKIT including the quest artifact will crash the game at startup.
C343-62 Unknown Riding into a magic portal gives an extra, useless message. You may be told "<steed> is still eating.", but it comes through with you regardless.
C343-63 Fix available [15] You can drink from a sink, fountain, or while underwater while swallowed. Confirmed in NH4 by quaffing from fountain while engulfed by purple worm. In a similar vein, #praying on a cross-aligned altar also works.
C343-64 Fix available [16] A black light leaves an hallucinated corpse while exploding.
C343-65 Fix available [17] A monster that "shrieks in pain" may not awaken others nearby. This is missing a wake_nearby call in the two relevant locations in potion.c.
C343-66 Fix available GruntHack Co-aligned unicorns in a bones file may be hostile. Happens when the unicorns were also co-aligned for the former player and he angered them before getting himself killed.
C343-67 Unknown Finding a statue when searching while blind doesn't update map.
C343-68 Unknown Incorrect message may be given when a spellcasting monster summons other monsters. may be a pluralization issue if extinction lets only one of the

monsters materialize.

C343-69 Fix available [18] Attempting to add more candles than needed to a candelabrum with at least one candle gives an incorrect message. bcode says: have six candles already attached, then try to attach more than one.
C343-70 Fix available GruntHack Experience may not be correctly gained for monsters causing nonphysical damage. "Difficult" attacks it possesses make a monster worth more experience, but the way these bonus points are calculated underrates physical damage.
C343-71 Fix available [19] When swapping places with a pet pushes it into a trap, the messages are out of order. "A gush of water hits Chmee's right forelimb! You displaced Chmee."
C343-72 Fixed UnNetHack You get confusing messages when you stop levitating while on a flying steed. "You float gently to the lava." is probably the silliest variant. The messages don't consider the fact that you're flying.
C343-73 Unknown Trying to kick a monster on a level forbidding teleport may give a bogus "teleports" message. "You kick the tengu. The tengu teleports, easily evading your clumsy kick." Fixed by Grunt.
C343-74 Fixed UnNetHack Entering a long running, uninterruptible command (e. g. engraving) after stoning starts will kill you.
C343-75 Unknown Eating Medusa's corpse may not work properly.
C343-76 Unknown A tin of Medusa meat isn't warned about properly. Warned as in from blessed scroll of food detection; no warning is given about it being "very dangerous", as with other monsters that cause petrification. (Medusa's corpse is also warned about incorrectly, warning about poison instead of petrification.) Fixed in GruntHack.
C343-77 Fixed GruntHack Some messages referring to monsters that look like horses refer to claws. polyself.c lists claws as a horse’s manipulatory appendages.
C343-78 Fix available [20] Digging in an existing hole charges you for the time it takes to dig the whole hole. To reproduce polymorph into vampire, wish for a pick-axe, apply said pick-axe down repeatedly. Alternatively, trigger a hangup-save after you finish digging and before you fall though.
C343-79 Unknown "Mr." or "Ms." may show up in front of names when it should not. In death messages, all shopkeepers will have an honorific, even if the shopkeeper's name is clearly a given name, not a surname (e.g. Dirk, Lucrezia, Izchak).
C343-80 Fix available [21] Tame monsters with multiple attacks may allow themselves to be killed through passive attacks. "The black unicorn misses the red mold. The black unicorn is suddenly very hot! The black unicorn misses the red mold. The black unicorn is suddenly very hot! The black unicorn is killed!"
C343-81 Fixed [22]+[23] Ghosts can be slimed.
C343-82 Confirmed GruntHack Land mine explosion on a drawbridge doesn't work right. Bridge over lava is replaced with a pit. Related to 343-240.
C343-83 Not a bug An eating pet will miss out on ascension.
C343-84 Fix available [24] "finally finished" may be displayed when not eating. Bug relates to the nomovemsg variable being left set and unmul() being called later for an unrelated reason. An easy way to trigger it is to eat lizard corpses off the floor with nothing in inventory but worn armor in the presence of several hostile nymphs while your nutrition is between 1500 and 2000. When it asks if you want to stop eating, say no. (You'll stop anyway as soon as a nymph seduces you, but saying no causes nomovemsg to remain set.)
C343-85 Help Sometimes the hero can't move when conscious. Very unclear description.
C343-86 Unknown Hero can appear to be in the wall after destroying a drawbridge.
C343-87 Unknown Sometimes shop items the hero is forced to buy can be sold twice.
C343-88 Fix available GruntHack Polymorphing a statue into a boulder can leave an incorrect display.
C343-89 Fix available GruntHack Unpaid objects damaged or improved in shops are not accounted for properly. If you pick up some armor and are quoted a price then read a scroll of enchant armor before paying, the price does not change UNLESS you drop the armor and pick it up again, in which case it then does. Enchant weapon works the same way.
C343-90 Fix available [25] "I u" with only one item unpaid lists the price twice.
C343-91 Fix available [26] Auto-cursing armor does not do so when worn by monster.
C343-92 Unknown A blind player may find a trap which then fails to show up on the map.
C343-93 Fix available GruntHack Astral vision can confuse the ; command. A monster on the opposite side of a solid maze wall may be said to be seen through normal vision as well as astral vision; in fact, normal vision cannot see it. At other times no mention is made of how you see something, even though it is only visible through astral vision.
C343-94 Fixed UnNetHack Probing a re-animated statue may cause a panic.
C343-95 Fixed GruntHack If killed by the wish from a magic lamp (or similar situation) and a bones file is produced, the bones file has the lamp in the wrong state. Create bones by using a magic lamp to wish for something that will blast you for more damage than you can survive. On loading the bones in another game, bless the lamp and rub it. A percentage of the time, you can get a second wish.
C343-96 Fix available GruntHack If player aborts "In what direction?" question, prompt may remain displayed. NH4 says, "What a strange direction!"
C343-97 Unknown ctrl + r and ctrl + l don't work in numberpad mode
C343-98 Fix available GruntHack Chatting with quest leader brought back from the dead doesn't work.
C343-99 Help Hero can still see for brief period after being blinded by potion vapors. If you kill a monster with a wielded potion of blindness and get blinded in the process, the corpse is shown, but I'm not sure whether this is a bug and also not sure whether this is what the bug description refers to.
C343-100 Fixed Bilious #341 Game may crash if thrown potion hits bars before a monster.
C343-101 Fix available GruntHack The hero can see some things while asleep.
C343-102 Unknown Messages delivered when the ceiling collapses on a swallowed hero need revision.
C343-103 Unknown The hero is not protected from a mind flayer during successful prayer. Refers to the psychic blast.
C343-104 Unknown Message from angry shopkeeper giving a price when hero picks up an object has poor spacing and construction. "For you, scum ; only 534 for this emerald ring." (note the extra space)
C343-105 Not a bug Message given when restoring a game refers to original gender and form, not current. I am not sure
C343-106 Fix available [27] Sunsword continues to glow after its wielder dies.

See Sunsword.

C343-107 Fix available GruntHack Killing your own steed never leaves a corpse.
C343-108 Unknown Entering "e-" does not remove the prompt.
C343-109 Fixed GruntHack There is a grammar error in the Tourist leader's greeting.
C343-110 Unknown Game can crash if shopkeeper dies while character is praying. Tried several times with strong pets and failed to reproduce in NH4.
C343-111 Unknown Grammar of some graveyard sounds messages is wrong in some cases. Alex Smith
C343-112 Help Hero and monster afflicted with lycanthropy are treated differently. How, where?
C343-113 Unknown When flying down a hole or a ladder, the messages are inaccurate. Doing this with a ladder while polymorphed actually produces no message at all. The message is most likely related to flying steeds, though; while riding a ki-rin, you climb up ladders, fly down ladders, and jump down holes, which is a clear inconsistency. (It's not clear which of the messages is correct.)
C343-114 Unknown GruntHack (fixes part of the problem) Removing some but not all the boulders from a location confuses the vision system. Fixed by Grunt [28][29]
C343-115 Fixed GruntHack Sleeping or paralyzed unicorns can catch gems.
C343-116 Fixed UnNetHack Grammar error in messages related to choking on gold.
C343-117 Unknown Gaining and losing levels in normal and monster form do not balance. I was an XL7 human tourist, polymorphed into an elf, lost two levels to a vampire, polymorphed back to human, and was XL4. I then polymorphed to elf again, lost one level, polymorphed back to human, and my new form was too weak to survive.
C343-118 Fixed [30]+[31] Some messages use "mirror" where they should use "looking glass."
C343-119 Unknown Options IBMgraphics, DECgraphics, and MACgraphics interact oddly in the config file, resulting in odd listings from the O command. Workaround: only specify one option in the config file.
C343-120 Not a bug There is no warning when hitting floating eyes.
C343-121 Confirmed Eating various brains which should have special handling, don't. You may eat brain of ghost and safely eat brains of Medusa and Riders as mind flayer.
C343-122 Fix available [32] Alignment of Angels is not handled consistently.
C343-123 Unknown Plural of "mother-in-law" is incorrect. Alex Smith
C343-124 Confirmed You can't rub a touchstone on gold. You can, but only if the touchstone is not formally identified. Fixed by Sean Hunt
C343-125 Unknown Killing a vault guard outside a vault gives incorrect feedback. Fixed by Grunt
C343-126 Unknown When wielding Grayswandir, feedback from a trapped chest may be wrong. If the chest trap is colored gas (which normally stuns and hallucinates), and you are not already stunned, the message is the same whether you have hallucination resistance or not. (However, the message does not specifically say anything about hallucination.)
C343-127 Unknown If a vault guard leads the hero to gold in the rock, inappropriate feedback is given. Fixed by Grunt
C343-128 Fix available GruntHack Feedback for gas spore explosion when hallucinating could be improved. If you or a monster are caught in the explosion, it is always called "the gas spore's explosion", one of the only situations wherein a monster's correct name is always used while you are hallucinating.
C343-129 Fix available [33] Cancelling objects in or near a shop doorway may make the shopkeeper think you are a thief. The error’s in zap.c, around line 794; it checks to see if you’re in the shop, rather than whether the object is.
C343-130 Unknown Sometimes you can't rub an arbitrary object on a touchstone. Perhaps this refers to the fact you cannot check for kicking boots and gauntlets of power once the touchstone has been formally identified. Fixed by Sean Hunt.
C343-131 Unknown Message has poor grammar if hero killed when stealing cockatrice corpse from a monster. Death message is "petrified by stolen cockatrice corpse"; it should be "petrified by a stolen cockatrice corpse".
C343-132 Unknown Message when death caused by kicking an object can be too verbose. Grunt says: I've thought that this refers to "killed by kicking a runed broadsword named Stormbringer" if the artifact was not identified, as opposed to "killed by kicking Stormbringer". The former behaviour has been acknowledged to be a bug to me in response to a related bug report of my own.
C343-133 Useless Effects of varying consuming Medusa are inconsistent. Description does not adequately differentiate this bug from C343-75, C343-76 and C343-121.
C343-134 Fixed GruntHack Being petrified by swallowing a cockatrice violates foodless conduct.
C343-135 Unknown Several quest messages are inappropriate if the hero is blind. The messages in question are ones issued upon entering certain levels for the first time. Arc, Cav, Tou, Wiz quests have issues that I noticed.
C343-136 Fixed UnNetHack A samurai quest guardian message uses "ninja" where "ronin" is intended.
C343-137 Fix available GruntHack [34] Demons may demand money from (and get paid by) a fainted hero.
C343-138 Unknown Some spheres pick up objects and some don't. Tame flaming and shocking spheres (at least) pick stuff up. Hostile ones don't, and you cannot if polyselfed into any kind of e, because you can't reach the floor.
C343-139 Unknown There's no feedback when an unseen drawbridge opens or closes. The first time you play the passtune, you get feedback no matter what. Subsequently, you only get feedback if you can see or if something interesting happens (e.g., a monster gets crushed).
C343-140 Unknown Pets may continue eating after being paralyzed or falling asleep. Actually, if you use a stethoscope in wizmode you see that their hunger is changed all at once when they start eating, and I'm pretty sure the corpse is removed at that time too; the only real multi-turn effect of a pet eating is the inability to move, which is redundant with sleep or paralysis.
C343-141 Fix available [35] Running, searching, and resting should stop wnen levitation ends. Quaff an uncursed potion of levitation and use a numeric prefix to rest for 9999 turns.
C343-142 Unknown Shopkeepers can be identified while hallucinating. Fixed by Grunt
C343-143 Unknown Leprechauns stealing gold from a mounted hero cause oddly worded messages. See steal.c, line 51
C343-144 Fix available GruntHack or [36] Creatures that can fit under doors can't fit through diagonal gaps. Tested with black puddings. Refers to diagonal passages through rock only (they do fit between boulders ok).
C343-145 Fix available GruntHack Mattock is mishandled when forcing locks. You bash a lock with a pickaxe (i.e. it is considered blunt), but pry with a mattock (i.e. bladed).
C343-146 Unknown Unseen wand of striking becomes known if zapped by unseen monster and it hits a door. mbhit calls doorlock, which returns true if anything happens; when doorlock returns true, mbhit calls makeknown without checking cansee
C343-147 Fix available [37] The game panics if a magic trap tames a monster that just expelled the hero. per Grunt: mon.c:583 still refers to the old invalid monster (more detail on rgrn).
C343-148 Unknown Changing locations while asleep lets you see objects or read engravings. " I didn't reproduce the described bug, but I did discover that upon waking up the display is not properly updated until you move. "
C343-149 Unknown Polymorphed spellbooks don't behave as intended. If the spell wasn't present in the spellcasting Z menu when you read the book, it is never blanked, regardless how many times it was already polymorphed. This bug also affects spells forgotten due to a non-blessed scroll of amnesia.
C343-150 Unknown Gender and/or size of some quest quest leaders and nemeses are wrong. By Jonadab: The following do not have a gender specified (in monst.c): The Grand Master, The Arch Priest, The Minion of Huhetotl, Ixoth, Master Kaen, Nalzok, Scorpius, The Master Assassin, and the Dark One. I'm guessing some of those should have a fixed gender. As for the size, the encyclopedia entries for Orion and for the Norn seem to imply they should be larger (currently they are MZ_HUMAN, i.e., medium size).
C343-151 Unknown Monsters can teleport to or be created outside of legal area in special levels. Examples are xorns off the map in Sokoban or ghosts on the edge of the map of the Astral Plane.
C343-152 Fix available GruntHack Using a cursed lamp while blind may give inappropriate messages. If it fails to light, even a blind character will observe that it "flickers for a moment".[1]
C343-153 Unknown Player polymorphed into guardian naga spits the wrong kind of venom. "Your venom burns the dog!" (I guess this is acid.) However, when a guardian naga attacks me, "The venom blinds you."
C343-154 Unknown Candles are fireproof. you can create fireproof candles by erodeproofing a wielded pick-axe, then polymorphing it. IIRC you can't wish for fireproof candles directly, and it doesn't make sense for a working candle to be fireproof Falling into lava does destroy them, but zapping with a wand of fire doesn't seem to (neither when they are in the player's possession nor when they are on the floor), nor falling into a fire trap (while holding them in open inventory).
C343-155 Fix available GruntHack Proper names may be incorrectly preceeded by "the" when hallucinating. Some of the capitalized entries in bogusmons should (and do) get the article ("The Ravenous Bugblatter Beast of Traal", "the Klingon", etc.), which is all very well, but others very clearly should not and yet currently do ("The Totoro", "The Barney the Dinosaur", "The Morgoth", "The Godzilla", "The Smokey the bear", "The King Kong"). The code needs a way to distinguish these two cases -- either two separate lists, or some kind of flag to indicate which ones that should not use "the". Allegedly fixed by Grunt; fix ported with fixups by Sean Hunt. Still not sure if it catches all cases.
C343-156 Unknown Reading scrolls may give redundant feedback messages. Read cursed remove curse while confused: "As you read the scroll, it disappears." ... "The scroll disintegrates."
C343-157 Unknown Worms don't have scales. Because worms have M1_SLITHY, mbodypart uses snake_parts for them, but it should not.
C343-158 Unknown Krakens have tentacles. mbodypart needs to special-case them; it does not.
C343-159 Fix available GruntHack Stalkers have a head. mbodypart uses vortex_parts for all v and E, but stalkers should probably get humanoid_parts instead.
C343-160 Fixed Name "leather spellbook" is misleading.
C343-161 Fix available GruntHack [38] A scroll of charging that has disappeared may still show in the list of things to charge.
C343-162 Fixed Ray Chason Upstream Using Magicbane may cause an ungrammatical message. Possibly refers to monster names incorrectly being considered as plural forms, e.g. "Chops are confused." with a monster named "Chops"
C343-163 Fix available "maybe" Antholes are mispopulated under some conditions.
C343-164 Unknown Cancelled nurses may give inappropriate messages. Believed to be related to #chat, she'll say things like "Take off your shirt, please" even though she can't do use the "attack" around which those messages are flavored.
C343-165 Unknown Scroll of mail can be abused slightly. Perhaps this refers to the fact shopkeepers will eventually start charging for mail if you pick up enough of them. Alternately, may refer to using the mail daemon on Astral to clear a path.
C343-166 Unknown Pits dug in vault guard's corridor don't get removed. Fixed by Grunt
C343-167 Unknown Length of time swallowed is sometimes calculated incorrectly.
C343-168 Fix available [39] Shattering a monster's weapon doesn't work right if the weapon is part of a stack of more than one.
C343-169 Unknown Autopickup fails during a failed untrap attempt. Player is involuntarily repositioned onto the trapped tile, but items there are not automatically picked up.
C343-170 Unknown Damage by silver weapons is sometimes higher than intended when hero is polymorphed. Perhaps this refers to the fact players hit multiple times with the same weapon if polymorphed into a form with several weapon attacks, e. g. Aleax or marilith.
C343-171 Fixed UnNetHack Silver weapon damage message is sometimes missing when hero is polymorphed.
C343-172 Unknown Crash could occur when monster uses potion or food to cure stoning or confusion.
C343-173 Unknown Monster eating lizard corpse is not handled correctly. jmminch says a monster eating a lizard corpse for confusion lost speed
C343-174 Fixed UnNetHack Drum of earthquake gives inappropriate message if hero or monster is in a pit.
C343-175 Fixed UnNetHackPlus Chatting to hostile prisoners may give an inappropriate message. There is a bug in description of the bug - it applies to tame prisoners (MS_DJINNI is mostly OK, but tame one - "Sorry, I'm all out of wishes." is weird).
C343-176 Fix available [40] Disintegration breath hitting equipment carried by monsters is not handled properly; if the monster life-saves the situation is worse; saddles are especially troublesome. Archive of report on rgrn "The invisible saddled ki-rin is not saddled."
C343-177 Moot First false rumor is displayed as gibberish on some platforms. I assume here that it affects something obscure like Amiga (UnNetHackPlus supports only windows and linux)
C343-178 Unknown Wisdom is mishandled when rumors are used for random graffiti. getrumor() exercises or abuses wisdom, which doesn't really make sense when it's being used to generate random graffitti on the floor.
C343-179 Fixed Bilious #340 If a monster is killed by a drawbridge while carrying a potion of acid, the game may panic.
C343-180 Help In an obscure case on special levels, troll corpses may fail to revive and lizard corpses may revive.
C343-181 Fix available [41] The hero is welcomed to Delphi even if the Oracle was previously angered.
C343-182 Unknown Putting on the Eyes of the Overworld while blind gives an ungrammatical message. "You are blasted by the pair of lenses' power! You are now wearing an Eyes of the Overworld. You can see!" Also, the possessive form (the Eyes of the Overworld's), which shows up if you are blasted by their power when they are identified, is arguable.
C343-183 Unknown Jumping over an already seen trap may give an ungrammatical message. "You pass right over a anti-magic field." The message is also semantically odd for a falling rock trap, due to the word "over".
C343-184 Unknown Levitation via worn equipment is not implemented for monsters.
C343-185 Confirmed No message is generated when attempting to name a monster that cannot be named by the player. Confirmed with shopkeepers.
C343-186 Unknown Some messages referring to "priestess" say "priest." uhitm.c hardcodes "The priest mutters a prayer."
C343-187 Unknown Meditating monsters continue meditating when affected by something which wakes sleeping monsters. For example, playing a leather drum does not awaken them.
C343-188 Unknown Specifying role and/or race and an invalid alignment in NETHACKOPTIONS or config file causes a misleading message. "Incompatible alignment."
C343-189 Fixed UnNetHack Temple donations and protection lost to gremlin attack interact incorrectly. Specifically, a gremlin steals only the effectiveness of divine protection, not the amount.
C343-190 Unknown Monsters can hide while trapped or holding the hero.
C343-191 Unknown When an unseen monster forces a polymorphed hero out of hiding, feedback is insufficient.
C343-192 Unknown If invocation is performed while hero is trapped, hero remains trapped.
C343-193 Unknown Polymorphed hero can fall into water once and crawl out twice.
C343-194 Unknown Saving and restoring a game while punished and swallowed sometimes loses the ball and chain. I read an uncursed scroll of punishment, tried to pick up ball but it burdened me, so I set it back down, then I got swallowed by a purple worm, saved, restored, and the ball and chain were gone.
C343-195 Unknown Glass wand thrown and broken in a shop is not charged for.
C343-196 Unknown Wielded light source may get missed by rust trap. According to Aardvark Joe, your lamp will go out if the water hits your body, but never if the water hits the arm wielding the lamp itself.
C343-197 Unknown Attacking a hidden monster sensed via ongoing monster detection is interrupted inapropropriately. "Wait! There's a snake hiding under an uncursed pear!" Yeah, I kind of knew that.
C343-198 Fixed UnNetHack Playing in a 20 or 21 line window can cause the game to crash.
C343-199 Fixed UnNetHack The database entry for "monk" has a typo. There should be a comma after the quotation. Traditional typesetting would do this: "No," replied the monk. Modern style (developed within the last thirty years) might put the comma outside the quote.
C343-200 Unknown In the quest, it's possible to accidently skip the locate level e. g. by falling down a hole several levels.
C343-201 Unknown Phrasing of message when one monster attacks another with stacked weapons is odd.
C343-202 Unknown Pushing a boulder onto a level teleporter trap could cause repeated messages. Happens about three times out of ten. "You push the boulder and suddenly it disappears! You push the boulder and suddenly it disappears!" May be triggered when the levelport selects the level you and the boulder are currently on, and the code runs again to select a different destination.
C343-203 Unknown Hero arriving on a very crowded level may land on a monster causing game state corruption and possibly a crash. mnexto failed (do.c)? Program in disorder - perhaps you'd better save. rloc(): couldn't relocate monster Program in disorder - perhaps you'd better save.
C343-204 Unknown Hero grabbed or engulfed due to conflict should be released when conflict ends. Not only are you not released, but it's not obvious how to get out without harming your pet.
C343-205 Unknown Changes in hallucination state are not reflected properly when also mimicing. "Oh wow! Everything feels so cosmic!" ... "You return to human form! Far out! Everything is all cosmic again!" Again? Also, the hiding is not relevant here; this bug can also be reproduced when polyselfing into other blind monsters, e.g., a gelatinous cube.
C343-206 Unknown Divine gifts resulting from #offer are identified when blind. If Stormbringer is gifted to a blind character, it will still be described as a "black sword"[2]. "quoting Blindness#Object_appearances: "The special attacks of the Tsurugi of Muramasa and Vorpal Blade always tell you the artifacts's appearance.[22][23][24][25] The gift you would receive on crowning as neutral or chaotic are made "seen" if you are already holding it."" [42]
C343-207 Unknown Certain items that should never be created in Gehennom can be created there. Most likely refers to spellbooks, although the circumstances are unknown. Possibly refers to objects generated in boxes/chests?
C343-208 Unknown Hero can be blinded while fainted. "You faint from lack of food. It explodes! You seem unaffected by it. You regain consciousness." Perhaps the dev team intended it to wake and blind you?
C343-210 Unknown Hero can "feel a bit steadier" while unconscious. Aardvark Joe says, eat a bat corpse, then quaff a potion of sleeping.
C343-211 Fixed UnNetHack Engraving under water gives a poorly worded message.
C343-212 Unknown If the hero is killed by a thrown potion of burning oil, the game will panic.
C343-213 Unknown Display of stinking cloud may be incorrect when wearing Eyes of the Overworld. Believed to be fixed in GruntHack.
C343-214 Unknown Monster escaping by changing levels in the wizard tower may end up outside the tower too easily. poke vlad with magicbane until he's confused and wounded. Assume he's created with a scroll of teleportation. He will read it, and levelport to any random level in the Dungeons of Doom, Gehennom abvoe his tower, and his tower. [43]
C343-215 Unknown Elbereth is sometimes ignored by monsters. Could refer to the need to "mark" the square with an item (an artifact of the effect originally belonging to the scroll of scare monster), or that Kops only respect Elbereth when you're on it.
C343-216 Unknown Fireproof containers catch fire in lava.
C343-217 Unknown Missile which kills engulfer is temporarily lost when hero is expelled. May refer to the missile being placed on the ground after the player is, rather than before, which can be noticed via autopickup.
C343-218 Fixed Bilious #342 Applying a wielded cream pie can crash the game. This generalizes to wielded objects being destroyed.
C343-219 Unknown Hero can die due to "burned by burning" or "drowned by drowning." A lot of similar combinations are possible by messing around with delayed_killer by stacking many delayed instadeaths on top of each other.
C343-220 Unknown Eating a Rider corpse doesn't work quite right. If you start eating it, die as a result, and lifesave, you can finish it safely. (The same thing happens to some other sort of corpses, like rotten ones, but not nearly as obviously.)
C343-221 Unknown Jabberwocks do not always wake up when they should.
C343-222 Fix available [44] It's possible to end up wielding a cockatrice corpse when no longer polymorphed.
C343-223 Unknown Hidden pet can follow hero down stairs, remain hiding and show up as hidden monster. Also can happen with a magic whistle. Tested with a tame scorpion hiding under an item. After traversing the stairs it was still hiding for a turn or two, even though there was nothing there to hide under.
C343-224 Not a bug Carrying too many items creates uselessly long prompts. Using a WIZKIT allows player to have too large amount of items, what results in prompts with repeated # sign (for example on dropping items). I do not consider it useless.
C343-225 Fix available [45] Hero can sometimes carry too many boulders. Even the number of available inventory slots is no obstacle when polymorphed into a titan.
C343-226 Unknown Inventory display doesn't mention unpaid items in a container the hero owns. The container is listed, but its contents are not even if unpaid. Not sure exactly what the expected behavior would be here.
C343-227 Unknown Container dropped in a shop then moved to an untended shop behaves oddly.
C343-228 Unknown Cloak of magic resistance is active when it shouldn't be.
C343-229 Unknown Hero can dip or apply grease to a worn item that is covered by another worn item. A similar effect applies to monsters getting dressed, while wearing a cursed cloak / body armor. You can #dip a shirt that's covered by DSM into holy water, but you cannot apply grease to DSM that's covered by a cloak.
C343-230 Unknown Drawbridges act differently depending on which direction they are pointing.
C343-231 Fixed UnNetHack Time is distorted while sinking into lava. Because lava sinking is checked once per player input (inexplicably), as opposed to once per player turn or once per time-consuming action.
C343-232 Fix available GruntHack Hero can be slimed while in lava.
C343-233 Confirmed Hero polymorphed into Quantum Mechanic may get erroneous messages about disappearing monsters. Moster teleported together with engulfed player: "%s suddenly disappears!". Monster teleported away, without player inside (happens in endgame) - no message. location of buggy code, this patch is not fixing second case
C343-234 Unknown Sacrifice on an altar can have unintended consequences. Perhaps this refers to the fact the corpse of a former pet does not vanish.
C343-235 Fixed UnNetHack Casting spell of protection gives incorrect message if hero is swallowed or in rock.
C343-236 Unknown Engraving works in places it shouldn't.
C343-237 Unknown The relationship between crossbow use and strength is wrong. This has been altered in SporkHack and debated on rgrn. In Next version, Pat Rankin said, "As far as crossbows go, they were changed some time back to shoot for maximum distance regardless of strength or dexterity, and to require high strength to retain full multi-shot volleys."
C343-238 Unknown (Unix and VMS only) The "Who are you?" prompt does not accept digits in the response. You can include digits in your answer, but if your answer starts with a digit the guard will just reprompt you.
C343-239 Unknown Engravings can transfer between a moat and a drawbridge. Engrave on the bridge, then step away and play the passtune.
C343-240 Unknown Hero can create a pit in air. Can be accomplished by setting a land mine and waiting for a monster to trigger it (or I suppose you could trip it yourself). Related to C343-82.
C343-241 Fix available GruntHack Hero is not charged for breaking the lock on a container owned by a shop.
C343-242 Unknown Shopkeepers and priests avoid graves when they should not. Priests will pick a random spot next to their altar, and try to go there whithout stepping into your line of attack. Game-play observation implies this "without" part also blocks them from stepping onto a (bones file) grave.

For example, if there's a grave on the tile directly inside the door of a shop, the keeper will not step there, making it easier than it should be for you to get in and out of the shop. You can walk in with a pick-axe in open inventory, for example, or walk out with shop merchandise (although in the latter case you face Kops and striking, and THEN the shopkeeper will finally step on the grave and come after you). I'm not sure exactly how this applies to priests, though.

C343-243 Fixed GruntHack Hero can throw without hands.
C343-244 Fix available [46] Sometimes you can eat artifacts you can't touch with your hands.
C343-245 Unknown Hero trying to kick beyond map edge is handled improperly. According to Aardvark Joe, "I suspect this bug refers to the fact that the code does not validate the location that you're trying to kick, and can end up accessing memory outside of the map structure, which can cause memory corruption. I'm able to recreate this in NH4 by kicking a location off of the edge of the map, and eventually end up with a segmentation fault."
C343-246 Fix available [47] Engraving with an empty wand handles time wrong. If you cancel the engraving text prompt or are levitating, no time is spent.
C343-247 Unknown A magic portal may be deactivated if the game is saved due to hangup while changing levels. The official buglist mentions "Leave the level some other way then return to it." as a workaround.
C343-248 Fix available Bilious #257[48] You can't put candles in a candelabrum while underwater.
C343-249 Unknown There are a number of errors handling vomit; and real rats can't vomit.
C343-250 Unknown Rust-causing targets can reveal other information about a weapon.
C343-251 Unknown Monsters sleeping due to being hit may wake up at the wrong time.
C343-252 Fixed UnNetHack There is a typo in the quote from "The Count of Monte Cristo."
C343-253 Unknown Choking on certain food items doesn't work properly.
C343-254 Unknown Shapechanger's don't take advantage of being mimics or hiders.
C343-255 Unknown Tinning on a full level fails improperly.
C343-256 Unknown Very very very long messages can cause a crash.
C343-257 Unknown Cursed corpses wielded by monsters are not handled properly. Perhaps this refers to the fact wielded items are always dropped when a monster polymorphs.
C343-258 Fixed UnNetHack Grammar error in samurai quest: "wakarimasu?" instead of "wakarimasu ka?"
C343-259 Fixed UnNetHack "Dr. Dolittle" is spelled incorrectly.
C343-260 Unknown Ridden steeds are sometimes immune to gas traps. Specifically, if the player has intrinsic sleep resistance, it protects the ridden steed as well.
C343-261 Unknown Sleeping steeds can jump. I get "you can't see where to land", no matter how well lit things are. Once the horse wakes back up, I can see to land just fine.

Can you or monsters kick your steed, causing it to jump and evade the kick?

C343-262 Confirmed Polyporph mis-handles a used and wielded leash. Polyself into something that cannot wield (e.g. a hell hound). "You find you must drop your weapon!" This leaves an in-use leash on the ground. Your pet can even pick it up, carry it around, drop it, and it's still listed as "(in use)".
C343-263 Fix available GruntHack Probing may miss Schroedinger's cat. The cat is created only when the container is opened, but should be when it is observed.
C343-264 Useless "You must drop your weapon" may appear when it should not. Assumed to be duplicate of C343-262
C343-265 Unknown Force may work when hero can't reach lock being forced. For example, while wearing a ring of levitation, you can #force the lock on a chest, but you cannot #loot it.
C343-266 Confirmed Hero on drawbridge when it's destroyed is not handled properly. Destroy a drawbridge by zapping a wand of striking or of digging downward while standing on the bridge. "The drawbridge collapses into the moat" without harming you, leaving you standing on the moat even if you are not properly equipped to stand there. Information has been posted to rgrn about the dev team's fix for this; to find the thread, search for phlebocratic postreticular apodiosis. ("It now calls spoteffects() for the hero or minliquid() for monsters. If the exposed terrain is water or lava, then the former bridge occupant will fall in (and hero might crawl out of the water); other under-bridge terrain is safe.")
C343-267 Unknown Game says monster speed changes even if monster can't move at all. Fixed in AceHack. Reproduced in NH4 by zapping wands of speed and slow monster at a red mold (which is sessile, according to the wiki).
C343-268 Fixed Bilious #340 Used up potion of acid may end up in bones file.
C343-269 Unknown Bones file created after hero dies outside shop may mis-handle items.
C343-270 Fixed UnNetHack Dying in a shop while wielding two weapons may cause a warning message.
C343-271 Unknown Pet messages at the very end of the game may appear in the wrong place.
C343-272 Unknown Corrupted score file can crash the game.
C343-273 Unknown Changing alignment and held artifacts interact incorrectly. E. g. you still enjoy the when-carried benefits of artifacts you could not pick up due to your current alignment.
C343-274 Unknown Odd message when attempting to apply a wielded towel. "You cannot use it while you're wearing it!"
C343-275 Fixed Bilious #342 If a lit, wielded, candle or potion of oil burns out, the game may crash.
C343-276 Fixed Bilious #342 If a figuring auto-transforms while wielded or worn, the game may crash.
C343-277 Unknown Wooden weapons don't always burn when they should.
C343-278 Unknown Quest leaders are too likely to be affected by traps.
C343-279 Unknown Kicked arrows may get wrong bonuses.
C343-280 Unknown Ranged polearm attack doesn't always work properly.
C343-281 Unknown Kicking shop-owned food is not always accounted for correctly.
C343-282 Unknown Damage calculation may be wrong when hero is polymorphed into a pudding.
C343-283 Unknown Long walks take a non-optimial path.
C343-284 Unknown Activating a shop-owned figurine sometimes don't entail shop charges. If you pick up and drop a cursed figurine, the timer will stay live. Will this eventually incur charges?
C343-285 Fix available add M1_UNSOLID flag Water elementals can be trapped in a bear trap.
C343-286 Unknown Polymorph and lycanthropy do not interact properly.
C343-287 Unknown Hero polymorphed into monster with kick attack doesn't get bonus from ring of increase damage when kicking.
C343-288 Unknown The message "a monster appears" can show up when multiple monsters appear.
C343-289 Unknown If magical removal of a steed's saddle is fatal to the hero, the saddle may still be on the steed in a bones file.
C343-290 Fix available GruntHack Rings do not show up in the "what do you want to charge?" prompt when they should. Applies to oil lamps, too.
C343-291 Unknown Backstab bonus interacts incorrectly with thrown weapons and two-weapon mode. Two-weapon does not get backstab at all while each fired weapon does individually.
C343-292 Unknown Touching a pile of objects while blind does not always work correctly.
C343-293 Unknown There are a number of errors changing words between singular and plural forms.
C343-294 Moot Orcs and gnomes do not respond to #chat when they should. #chat responses from monster are completely reworked
C343-295 Unknown Casting stone-to-flesh on self while wielding a figurine can cause the game to panic.
C343-296 Unknown Sunsword doesn't work as expected against shades.
C343-297 Unknown Lit potion may survive hero dying from splattered oil burning on the floor.
C343-298 Fixed UnNetHack Kicking at "empty space" uses no time.
C343-299 Fixed UnNetHackPlus Killing tame engulfer from inside gives a warning message.
C343-300 Unknown Amulet of strangulation may kill forms that can't be strangled.
C343-301 Unknown Nymphs can steal things they can't pick up. They can steal Rider corpses from gelatinous cubes. The bug might instead refer to nymphs stealing things that they don't naturally pick up, like potions.
C343-302 Fixed [49]+[50] Amnesia of object discoveries may forget to forget one thing. Thanks to read.c#line501 player doesn't forget anything when the "count * percent" is smaller than 50. In other words player that knows identify of single object will never loose memory of it via mind flayer attack. IMHO in addition forget_objects should forget percent% of objects, rather than floor(percent% + 0,5% of objects)
C343-303 Unknown Gem probabilities are not reset properly on level revisit.
C343-304 Unknown Message given when damaging a closed drawbridge may refer to a wall.
C343-305 Fixed GruntHack Attacking with an applied polearm ignores the "confirm" option.
C343-306 Unknown Engulfer under influence of conflict or confusion can swallow a monster and not be affected by water/lava/trap under monster until next turn.
C343-307 Moot UH in UNH is unable to restore attributes Unicorn horn interacts incorrectly with ring of sustain ability. Non-cursed restores, but cursed does not decrement attributes.
C343-308 Fix available GruntHack A hidden, dead monster can revive hidden under its own corpse.
C343-309 Unknown Dropping Heart of Ahriman may give odd message sequence.
C343-310 Unknown Applying an unpaid stack of potions of oil forces hero to buy all of them.

C343-315 Unknown Small monsters dropping items due to weight use the wrong weights.
C343-316 Unknown Monsters who shouldn't will attack the Wizard to get the Amulet. See also SC343-19.
C343-317 Unknown Bones data can contain odd characters from player's dogname, catname, or fruit options; this can cause odd terminal-dependent behavior. NetHack fails to sanitise characters taken from options.
C343-318 Fixed UnNetHack Opening or closing the castle drawbridge using music takes no time.
C343-319 Unknown Grid bugs can be forced to move diagonally, e. g. by displacing a tame one.

C343-324 Fixed Bilious #332 Cutting a long worm in two will crash the game if the cut takes the worm to 1 HP or if long worms had become extinct.
C343-325 Unknown Hole in ice may be described as a "moat."
C343-326 Unknown Open and close commands may give inappropriate feedback near a drawbridge.

C343-330 Unknown Wrong message may be delivered when seeing a pet eating.

C343-339 Unknown Screen and time are not always updated properly when opening or closing doors while blind.

C343-342 Unknown Potion thrown by monster which hits long worm's tail says it hit its tail.

C343-371 Unknown Stethoscopes can sometimes be used more often than intended. If you save and resume, you can use it again for free. On an aside, saving and restoring loses the movement points you gain from speed, and makes your exercise prior to the save worth less.
C343-372 Unknown A fatal explosion can give the player messages in the wrong order if carried items are destroyed.
C343-373 Unknown Shopkeepers can polymorph into forms that don't let them do their jobs. A blue jelly shopkeeper will buy and sell, but it won't move to block or unblock the door.

C343-381 Unknown Attacking by applying a polearm doesn't scuff engraving under hero.
C343-382 Fix available GruntHack Auto-wielding a polearm may take no time. Does this also apply to pick-axes when you start digging? I am not sure whatever it should take time.

C343-401 Unknown Wearing an elven cloak identifies it even if hero is already stealthy.
C343-402 Unknown Putting on a ring of stealth never identifies it. A workaround is to check if putting on elven boots gives a message.

C343-417 Unknown Polymorphing into a human form may give a message with the wrong gender.
C343-418 Unknown Weight of non-cursed bag of holding is sometimes off by one. Possibly, this refers to multiple stacks of gold in any bag: two stacks of $49 weigh 0, but one stack of $98 weighs 1. This might relate to shop-owned versus hero-owned gold.
C343-419 Unknown With option number_pad set to 2, M + 5 (or Alt + 5 or Shift + Keypad5) does not work as the G movement prefix.
C343-420 Unknown Kops may not be dismissed if the shopkeeper changes levels. You might want to pacify the shopkeeper on his home level. If necessary, steal a gold piece and pay him off again.

SC343-12 Fixed Bilious #337 Hero using telepathy can abuse Call on the Astral Plane.
SC343-13 Unknown While blind and levitating, too much information may be presented. Does this refer to messages about monsters scared by an Elbereth engraving? Or typing > to identify the stairs?

Bugs not mentioned on the DevTeam's website

Name Status Patch Description
C343-204 Unknown The hero can teleport on a non-teleport level: Get engulfed by a tame engulfer using conflict, end conflict, apply a magic whistle.
Unknown The boulder from a rolling boulder trap can be generated on top of a lava pool. [3]
Unknown It is impossible to paste (e. g. "ElberethElbereth") into the windows tiles build. This works on OS X, however.
Unknown The game sometimes behaves as if a series of spurious non-attacking movement commands were typed after #looting a container.
Unknown Confused #looting a throne does not destroy it.
Unknown The "hilite_pet" option does not work on monsters only seen due to the monster detection spell.
C343-391 ? Unknown Polymorphing a cloaked pet mimic (by whistling it onto a polytrap) does not unhide it, even if it turns into a non-mimic.
Unknown You can reliably trigger clairvoyance (donation, cornuthaum, Amulet) by far-looking ; or wall-walking on turns divisible by 15 until your surroundings are mapped.
Unknown Killing a monster with a rolling boulder trap breaks pacifist conduct if and only if the trap was not known.
Fixed UnNetHackPlus You can't bribe the watch.
Unknown Jabberwocks can wield things and hit monsters with them, but monsters will not get petrified, take silver damage, etc. (Report)
Unknown Declining to attack a peaceful monster still burns nutrition without using up the turn.
Fix available GruntHack Declining to kick a peaceful monster still uses up a turn and wakes nearby monsters.
Unknown Turns do not alternate correctly if the player has 24 movement energy exactly, and a monster has at least 24 movement energy. (Report)

Unknown Lifesaving during slow engraving causes the engraving to appear on the ground before it should be completed, but (even if an Elbereth) not be effective at scaring monsters until it would have been completed.

Unknown While using #twoweapon, if slippery fingers cause both weapons to slip from your hands, on the same turn, the messages can seem rather odd. (rgrn post)
Unknown Praying[4] or fainting[5] resets the "sound" option to true.
Unknown Freshly slain corpses stack inconsistently: Say there is a stale stack of corpses on your altar. A way of making the fresh corpses created not get 'oldified' by the existing stale stack is to blind yourself when killing the new puddings; somehow this causes the newly generated corpses to be in a different stack.
Unknown Moving with the m or HJ... commands into a warning symbol attacks (and stones you if applicable) if and only if it does not cover up an I known from previous searching or movement. (see also: m, todo: document at cockatrice, warning, stethoscope.) Things are even more complicated if you are blind, or if there are invisible monsters you can't see.

Testing a blind player with a peaceful shopkeeper: If you apply a stethoscope and it says Akalapi is there, and then "you move into it", without "Pardon me, Alikapi.", and he doesn't get angry.

Unknown If you rename the statue or corpse of a unique monster, then reanimate/revive it, the unique monster will keep its new name permanently (and also gain a "the" prefix if its actual name has one).
Unknown Wielding or alternate-wielding or quivering a potion of blindness will make you resist blindness from yellow lights and archons. (report)
Unknown If the player dies and is lifesaved, then the game will leave them helpless until the next turn, except if they were repeating a command using a numerical prefix and at least one more repeat is left, in which case they are not left helpless and (if they died while performing the action, rather than on a monster turn) the movement energy used to perform the action is refunded.
Fixed UnNetHack Picking up gold doesn't honor the setting of pickup_burden if the game is compiled without GOLD_OBJ (no prompt when the encumbrance level is exceeded).
Unknown Demon gating produces somewhat more incubi than succubi, especially on lower dungeon levels. Cause: Makemon.c#line1352. (User:Ilmari Karonen computed exact number some time ago.)
Unknown A SUBROOM with random size and location is always generated at the top or left edge of the parent ROOM.
Fixed Fix from Pat Rankin UnNetHack impossible() can mangle the parameter values.
Unknown Jumping into portals with an item immediately before the portal prints messages out of order, and also autopickups the item (despite jumping over items not normally picking them up). (report)
Unknown The travel command gets interrupted by engravings, even by dust engravings while blind. In every other respect, the game behaves as if you cannot feel the dust engraving while blind.(first observed by JoveHack)
Fixed UnNetHackPlus (note preceding refactoring Statues/figurines of golems hit with stone-to-flesh spell are supposed to turn into flesh golems, not meatballs.
Unknown A player vampire lord who is wearing water walking boots and polymorphs into a non-flying form, will wet his stuff despite wearing water walking boots. A potion of levitation prevents this. (original report, source pointer, see also C343-193)
Fixed UnNetHackPlus Stethoscope reports unaligned monsters as chaotic

Confirmed Corpse stacking ignores age Easy to test with sacrificing - produce lizard corpse, drop on altar, wait till it is too old for sacrificing, produce new lizard corpse, drop it on altar. Corpses will stack and both will be too old for sacrifice. Now produce next lizard corpse and sacrifice it to confirm that "Nothing happens" is caused by old age of offered corpse.
Confirmed Pick up unpaid oil potion in shop, lit it, pay Fuel Tax, drop and sell it for more than you lost on Fuel Tax
Confirmed Attacking with polearm and dealing no damage will not violate conduct - see Apply.c#line2421 in use_pole function.
Fix available NitroHack by tung Upstream fleeing monsters getting stuck in corridors
Fixed Bilious #165 Two bugs relating to items vanishing from cursed bags of holding. 1) It doesn't use up a turn. 2) If it causes you to become unencumbered, the message saying so doesn't come until the following turn.
