Core bugs

Name Fixed in GruntHack Description Additional info
C341-1 fixed Monsters affected by stinking cloud always get angry at the hero even if the hero did not create the cloud.
C341-4 fixed opthelp does not list use_inverse
C341-5 Help When you see your pet move, the pet may be referred to as "it". What are the circumstances in which this occurs?
C341-7 fixed Skilled or expert caster of fireball/cone of cold can't target a monster known only by infravision or ESP.
C341-10 Open Fruit names ending in "us" are incorrectly considered plural. There's a possibility that this will be left alone, given that addressing it may cause more problems than it's worth.
C341-18 fixed ki-rins and couatls can wear (and may have) armor. Shields, boots, gloves, and (non-metallic for ki-rin) helmets.
C342-12 Help There are a number of places that misuse "your". What are these places?
C342-13 Help Hangup can cause loss of objects being moved internally. What are the circumstances in which this will occur?
C342-16 fixed If you self-genocide while polymorphed, the death message makes no sense. The message just before death is now "As you return to <racial> form, you die."
C342-19 fixed Things that can kill you in the future (like stoning) can cause messages to show up out of order. The dialogue display is now immediately before the timer is decremented and checked, so if you die to stoning, the last message you see is now guaranteed to be "You are a statue."
C342-22 fixed Monsters can hide under cockatrice corpses without getting stoned.
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.
C342-36 fixed If unable to see yourself while invisible and you are bestowed a spellbook, it doesn't show up on the display.
C342-46 fixed Cleric cast lightning doesn't blind as other lightning does.
C342-50 Help If you're hiding on the ceiling and try to #sit, you automatically unhide. Not reproducible by the author; possibly already fixed?
C342-51 fixed The game thinks trappers hide on the ceiling. This happened in two known cases: dislodging one with a drum of earthquake, and ambushing a creature while player is hiding as a trapper.
C342-54 fixed Statues of unique monsters in bones files are not handled correctly. Where a corpse of the monster would disappear, the statue is converted to a doppelganger instead of remaining tied to the unique monster's data.
C343-1 Help At a pit the game can give messages with poor grammar. What messages?
C343-2 fixed Wielded silver arrows don't cause silver damage on some silver-haters.
C343-3 fixed In the ranger quest, monsters can end up off the map to the left. The special level loader introduced a two column gap to the left of the maze; it's been adjusted to not add that two column gap.
C343-4 fixed On the Rogue level, tunnelling through rock doesn't leave a passage. This happened only with tame digging monsters, such as umber hulks. Since non-tame monsters can't dig on the Rogue level, pets can no longer dig on the Rogue level and this issue is addressed.
C343-5 fixed In wizard mode, level teleport in the endgame can cause a crash if confused.
C343-6 fixed You can #sit on an object at the bottom of a pit that you are not in.
C343-7 fixed When a steed pushes a boulder into a pool, the message misuses "you".
C343-8 fixed Plural of Nazgul is Nazgul - not Nazguls.
C343-9 fixed Trap messages referring to a named steed when hallucinating are poorly worded.
C343-10 fixed If there is a corpse in a pit, you have to enter the pit to pick it up but not to eat it.
C343-11 fixed 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 You can't use '>' to enter a pit.
C343-13 fixed On polymorph, you can get the message "It turns into it".
C343-14 fixed The initial and any tombstone message resulting from eating an identified artifact is gramatically incorrect.
C343-15 fixed You can get a message that an invisible monster looks much better.
C343-16 fixed Player polymorphed as a xorn can't pick up items in pits.
C343-17 fixed After polymorphing into a xorn and returning to human form, player can be stuck in a pit that isn't there.
C343-18 fixed Scaring a mimicing mimic gives an incorrect "turns to flee" message.
C343-19 fixed Dipping acid in a fountain may not destroy the acid.
C343-20 Open When dying immediately on entering a level, the map may show you dying on the previous level. This doesn't matter - mostly.
C343-21 Open Pets can be pulled through closed doors with a leash.
C343-22 fixed You can untrap a monster in a pit while levitating.
C343-23 fixed Dungeon collapses after vault guard fails to lead you out. A detailed write-up as to the cause of the bug is at C343-23. Fixed by checking if the guard is at his destination position and unable to move, and generating a new destination position if so.
C343-24 fixed Documented default for option "null" is "off"; default is actually "on".
C343-25 fixed You can trip over a cockatrice corpse safely.
C343-26 fixed A frozen swamp may be called a moat.
C343-27 fixed Kicked objects do not slide properly on air or water levels. There's a d3 bonus to distance applied for objects sliding on ice; this bonus is now also applied to objects sliding through the air.
C343-28 fixed There are several places that can't tell the diffence between a "hat" and a "helmet." All over the place. Currently soft helms as well as elvish helms ("hat" when unknown) dwarvish helms ("hard hat" when unknown) are referred to as hats.
C343-29 fixed When taking things out of a bag of holding, messages may say "lifting" instead of "removing."
C343-30 fixed Cursed scroll of destroy armor on cursed armor doesn't always interact correctly. Employing a cursed scroll of destroy armor on an stat-adjusting item now lowers the stat bonus from the item properly.
C343-31 fixed If you hit a cockatrice with a weapon that breaks, you can be stoned.
C343-32 fixed When blind and levitating, the hero can still discover stairs.
C343-33 fixed Sometimes a monster may remain hidden under a corpse that has rotted away.
C343-34 fixed Mimics on the rogue level may try to mimic a closed door.
C343-35 Help Polymorphed or shapechanged monsters may get the wrong number of hit points. Outside of the possibility that this refers to some type of rounding error, is this otherwise working incorrectly?
C343-36 fixed Weight of corpses on special levels may not be calculated correctly. This also goes for statues, e.g. the Oracle centaur statues.
C343-37 fixed Mimics may mimic a boulder over a pit or hole.
C343-38 fixed Dismounting and kicking a monster that jumps may result in landing on the wrong side of a wall. The relevant code now ensures that the monster can move to a tile adjacent to the player before actually moving it (otherwise it simply "blocks your clumsy kick" without moving).
C343-39 fixed Restoring a game where the character is wielding Sting may result in temporary display errors during the restore process. Worse than described: restoring a game where the player is wielding Sting while mounted would usually result in a crash as opposed to a display error. The equipping of inventory objects is now deferred until after monster chains as well as steed and stuck monster data has finished, ensuring the correct data is available for the specific warning code.
C343-40 fixed Monster thrusting one of multiple wielded daggers gives misleading message. More a problem with the wielding than the attacking; the monster's only actually using one of the stack. As such, the wield message now refers to the stack in the singular.
C343-41 fixed A rolling boulder falling into a pit you can't see only makes a sound if the hero is blind. You hear rumbling in the distance. You hear a distant CRASH! (Also, "the boulder fills a pit" when blind is now changed to "You hear a nearby CRASH!" if you could see where the boulder and pit are, or "You hear a distant CRASH!" otherwise; if you can't see the boulder or pit, how do you know that's what happened?)
C343-42 fixed If a fire trap melts ice, it may trigger twice in the same turn.
C343-43 fixed An invisible troll that revives may be shown until it moves. Seemingly fixed by invisible object handling: the corpse is invisible, and the invisible status is inherited from the corpse during the reviving process before this becomes a problem.
C343-44 fixed Shopkeepers, doors, and traps interact oddly. Traps in shops are now more consistently repaired (e.g. pits and holes from a wand of digging).
C343-45 fixed 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 fixed Monster and hero have different odds to err when throwing a greased weapon. Previously, monsters throwing projectiles didn't check if the projectile was greased.
C343-48 Help Killing your pet doesn't get you any experience when it should. Some special circumstance must apply here, as killing a pet normally in vanilla and in GruntHack does earns you experience.
C343-49 fixed The boulder does not show up in a bones file caused by death by rolling boulder. The boulder now finishes rolling before damage is dealt to the player, leaving the trap ready to be used again for the next unsuspecting victim should the player die and leave bones.
C343-50 fixed A sleeping steed may answer a #chat.
C343-51 fixed Luck's effect on random events isn't always as intended. GruntHack contains an alternate algorithm for rnl().
C343-52 fixed Worn or wielded objects destroyed by dipping into lit potions of oil are not handled properly; this can result in odd game behavior.
C343-53 Help If a shopkeeper is trapped adjacent to the door, the game may get confused and issue impossible or panic messages. Unable to reproduce for several definitions of 'trapped', including being stuck in various types of trap, surrounded by boulders, surrounded by blue jellies, etc.
C343-54 fixed "Ulch" cannibalism message grammar is poor. It now produces two messages: "You cannibal! You will regret this! Ulch - that meat was tainted!"
C343-55 fixed "Ulch" messages have inconsistent capitalization. "Ulch - That <object> was rustproofed!" to "Ulch - that <object> was rustproofed!"
C343-56 fixed Gas spores can't attack while hero is praying. Listed as fixed on the assumption that this referred to a spurious "The gas spore starts to attack you, but pulls back" message which has been addressed.
C343-57 fixed #enhance command descriptions in Guidebook and game do not match.
C343-58 fixed #conduct command description grammar is poor It's arguable whether the original message, "list which challenges you have adhered to", is grammatically incorrect (the author doesn't believe it is), but it's not necessarily very clear. GruntHack changes it to "list status of voluntary challenges", which is clearer, and does not suffer from grammar issues.
C343-59 fixed Engulfer stoned swallowing hero polymorphed to cockatrice causes incorrect screen display. If hero has ball & chain, game can panic. Expulsion from monster is now handled correctly, and ball and chain are replaced on map properly.
C343-60 Help Several messages delivered when hero's fingers are slippery have poor grammar. Which messages? (Not thoroughly investigated by the author.)
C343-61 fixed Using a WIZKIT including the quest artifact will crash the game at startup. Wizkit loading was before the quest text was loaded, causing a crash when the "picked up the quest artifact" message tried to be displayed. Wizkit loading now takes places after quest text is loaded.
C343-62 Help Riding into a magic portal gives an extra, useless message. Has not yet been reproduced by any known means.
C343-63 fixed You can drink from a sink, fountain, or while underwater while swallowed. In a similar vein, #praying on a cross-aligned altar also works.
C343-64 fixed A black light leaves an hallucinated corpse while exploding. It (and other exploding monsters) are now removed from the map while the effects of the explosion are calculated.
C343-65 fixed A monster that "shrieks in pain" may not awaken others nearby.
C343-66 fixed Co-aligned unicorns in a bones file may be hostile. Monsters' peaceful status is now reset when loading a bones file.
C343-67 fixed Finding a statue when searching while blind doesn't update map.
C343-68 Superseded Incorrect message may be given when a spellcasting monster summons other monsters. This code is no longer active in GruntHack.
C343-69 fixed Attempting to add more candles than needed to a candelabrum with at least one candle gives an incorrect message. Formerly "You attach 1 more candles to the candelabrum" in that specific case. Now properly prints "1 more candle".
C343-70 fixed Experience may not be correctly gained for monsters causing nonphysical damage. Actually, the opposite is more likely to be true - monsters dealing only physical damage were probably gaining too much experience; cf. vanilla exper.c#line76 and the commentary on the site.
C343-71 fixed When swapping places with a pet pushes it into a trap, the messages are out of order. Now "You displace <foo>.", printed before the results of the action are computed and always printed.
C343-72 fixed You get confusing messages when you stop levitating while on a flying steed. Previously "You float gently to the <floor>." even if flying; now if flying, it is "You lose some altitude."
C343-73 fixed Trying to kick a monster on a level forbidding teleport may give a bogus "teleports" message.
C343-74 fixed Entering a long running, uninterruptible command (e. g. engraving) after stoning starts will kill you.
C343-75 fixed Eating Medusa's corpse may not work properly.
C343-76 fixed A tin of Medusa meat isn't warned about properly.
C343-77 fixed Some messages referring to monsters that look like horses refer to claws. polyself.c listed "foreclaw" as the horse equivalent for hands; it is now "forehoof" (this overlaps with fingers, but the author considers that acceptable).
C343-78 fixed Digging in an existing hole charges you for the time it takes to dig the whole hole. You can no longer dig downwards when standing on top of a hole or a visible trap door. (If you try to dig through a previously unspotted trap door - is that possible outside of wizard mode? - it triggers the trap.)
C343-79 Open "Mr." or "Ms." may show up in front of names when it should not.
C343-80 fixed Tame monsters with multiple attacks may allow themselves to be killed through passive attacks. max_passive_damage assumed the monster would only make one attack; now it checks how many attacks the monster can make.
C343-81 fixed Ghosts can be slimed. All incorporeal monsters are now slime-resistant.
C343-82 fixed Land mine explosion on a drawbridge doesn't work right. The drawbridge is now destroyed, as expected.
C343-83 fixed An eating pet will miss out on ascension.
C343-84 fixed "finally finished" may be displayed when not eating. One way to generate this bug in other variants: get interrupted while eating, polymorph into a floating eye, and apply a mirror to yourself - when you unfreeze, you get "You're finally finished." Fixed by ensuring that nomovemsg gets set in all cases (perhaps it should be incorporated into nomul).
C343-85 Help Sometimes the hero can't move when conscious. Very unclear description.
C343-86 Open Hero can appear to be in the wall after destroying a drawbridge.
C343-87 Open Sometimes shop items the hero is forced to buy can be sold twice.
C343-88 fixed Polymorphing a statue into a boulder can leave an incorrect display.
C343-89 fixed Unpaid objects damaged or improved in shops are not accounted for properly. If positive change, the value of the object on the bill increases; if not, the shopkeeper charges you for the undamaged object.
C343-90 fixed "I u" with only one item unpaid lists the price twice.
C343-91 fixed Auto-cursing armor does not do so when worn by monster. Loadstones now also auto-curse when dropped by a monster.
C343-92 Open A blind player may find a trap which then fails to show up on the map.
C343-93 fixed Astral vision can confuse the ; command. Previously, monsters seen only with astral vision would also be listed as being seen with normal vision.
C343-94 Superseded Probing a re-animated statue may cause a panic. Apparently, related to the fixed SC343-8.
C343-95 fixed 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.
C343-96 fixed If player aborts "In what direction?" question, prompt may remain displayed. "Never mind" is now always displayed if this prompt is cancelled.
C343-97 Open ctrl + r and ctrl + l don't work in numberpad mode
C343-98 fixed Chatting with quest leader brought back from the dead doesn't work.
C343-99 Open Hero can still see for brief period after being blinded by potion vapors.
C343-100 fixed Game may crash if thrown potion hits bars before a monster.
C343-101 fixed The hero can see some things while asleep. The player is now treated as blind and non-telepathic when asleep or unconscious.
C343-102 Open Messages delivered when the ceiling collapses on a swallowed hero need revision.
C343-103 fixed The hero is not protected from a mind flayer during successful prayer.
C343-104 fixed Message from angry shopkeeper giving a price when hero picks up an object has poor spacing and construction.
C343-105 Not a bug Message given when restoring a game refers to original gender and form, not current.
C343-106 fixed Sunsword continues to glow after its wielder dies. This was only the case for monsters, and it behaves as expected now.
C343-107 fixed Killing your own steed never leaves a corpse.
C343-108 fixed Entering "e-" does not remove the prompt. Actually happened with any object prompt where - wasn't a valid choice, e.g. "a-"; "Never mind." is now printed in those cases.
C343-109 fixed There is a grammar error in the Tourist leader's greeting. "Is it really you, <player>!" is now "It is really you, <player>!"
C343-110 Open Game can crash if shopkeeper dies while character is praying.
C343-111 Open Grammar of some graveyard sounds messages is wrong in some cases.
C343-112 fixed Hero and monster afflicted with lycanthropy are treated differently.
C343-113 Open When flying down a hole or a ladder, the messages are inaccurate. Doing this with a ladder actually produces no message at all. (But that may itself be the bug.)
C343-114 fixed Removing some but not all the boulders from a location confuses the vision system. In particular, there was no check to see if there were other boulders at the location for the purpose of unblocking it, so the square was unblocked when the first boulder was removed.
C343-115 fixed Sleeping or paralyzed unicorns can catch gems.
C343-116 fixed Grammar error in messages related to choking on gold.
C343-117 Open Gaining and losing levels in normal and monster form do not balance.
C343-118 fixed Some messages use "mirror" where they should use "looking glass."
C343-119 Open 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 Open Eating various brains which should have special handling, don't.
C343-122 fixed Alignment of Angels is not handled consistently. Checking the alignment of a non-minion Angel reported it as "neutral", not the "lawful" that it is internally.
C343-123 fixed Plural of "mother-in-law" is incorrect.
C343-124 fixed You can't rub a touchstone on gold. Only if the touchstone was identified; see C343-130.
C343-125 fixed Killing a vault guard outside a vault gives incorrect feedback. Previously, you would consistently see "The corridor disappears", even if the corridor was already removed and/or not visible from where you are.
C343-126 Open When wielding Grayswandir, feedback from a trapped chest may be wrong.
C343-127 fixed If a vault guard leads the hero to gold in the rock, inappropriate feedback is given. Previously, "The guard (calms down and) picks up the gold." regardless of whether you just dropped the gold. That message is now only displayed if the gold is at your position (i.e. you just dropped it), with the message being "The guard picks up some gold" otherwise.
C343-128 fixed Feedback for gas spore explosion when hallucinating could be improved. While hallucinating, all explosion appearances are now randomised; a random monster name is substituted for "gas spore" when a gas spore explodes.
C343-129 fixed Cancelling objects in or near a shop doorway may make the shopkeeper think you are a thief.
C343-130 fixed Sometimes you can't rub an arbitrary object on a touchstone. Previously, after a touchstone was identified, you could only rub gems on it; it can now do so after the touchstone is identified.
C343-131 fixed Message has poor grammar if hero killed when stealing cockatrice corpse from a monster. Previously "petrified by stolen <object>", e.g. "petrified by stolen cockatrice corpse"; now "petrified by stealing <an object>", e.g. "petrified by stealing a cockatrice corpse".
C343-132 fixed Message when death caused by kicking an object can be too verbose. Presumably refers to "killed by kicking a runed broadsword named Stormbringer" and other artifact messages; death by kicking an object now treats the object as fully identified, e.g. "killed by kicking Stormbringer".
C343-133 Help Effects of varying consuming Medusa are inconsistent.
C343-134 fixed Being petrified by swallowing a cockatrice violates foodless conduct. Listed as fixed on the assumption that the bug refers to the absence of the described behaviour - swallowing a cockatrice whole in vanilla does not violate foodless conduct, but does in GruntHack.
C343-135 Open Several quest messages are inappropriate if the hero is blind.
C343-136 fixed A samurai quest guardian message uses "ninja" where "ronin" is intended. Listed as fixed on the assumption that this refers to the original message 09, "If The Tsurugi of Muramasa is not returned, we will all be ninja.", in comparison with message 14, "Lord Sato still lives! You have saved us from becoming ronin."
C343-137 fixed Demons may demand money from (and get paid by) a fainted hero. They'll now wait until you wake up for you to make their demand.
C343-138 Open Some spheres pick up objects and some don't.
C343-139 Open There's no feedback when an unseen drawbridge opens or closes.
C343-140 Open Pets may continue eating after being paralyzed or falling asleep.
C343-141 fixed Running, searching, and resting should stop wnen levitation ends.
C343-142 Open Shopkeepers can be identified while hallucinating.
C343-143 Open Leprechauns stealing gold from a mounted hero cause oddly worded messages.
C343-144 fixed Creatures that can fit under doors can't fit through diagonal gaps.
C343-145 fixed Mattock is mishandled when forcing locks. "You force your dwarvish mattock into a crack and pry." as opposed to "You start bashing it with your dwarvish mattock."; there's now an exception made for the mattock, and it is now treated as a bashing tool for the purpose of forcing locks.
C343-146 Open Unseen wand of striking becomes known if zapped by unseen monster and it hits a door.
C343-147 fixed The game panics if a magic trap tames a monster that just expelled the hero.
C343-148 Open Changing locations while asleep lets you see objects or read engravings.
C343-149 Open 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 Open Gender and/or size of some quest quest leaders and nemeses are wrong.
C343-151 Open 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 fixed Using a cursed lamp while blind may give inappropriate messages. Previously, "Your lamp flickers, then dies." Now when blind, the message is "Your lamp doesn't seem to have lit."
C343-153 Open Player polymorphed into guardian naga spits the wrong kind of venom.
C343-154 Open Candles are fireproof.
C343-155 fixed Proper names may be incorrectly preceeded by "the" when hallucinating.
C343-156 Open Reading scrolls may give redundant feedback messages.
C343-157 Open Worms don't have scales.
C343-158 Open Krakens have tentacles.
C343-159 fixed Stalkers have a head. The bug apparently means that stalkers should have a head; they're now considered humanoid (and an exception in mbodypart() to the rule that all elementals are amorphous has been made for them).
C343-160 fixed Name "leather spellbook" is misleading. Now "leather-bound spellbook".
C343-161 fixed A scroll of charging that has disappeared may still show in the list of things to charge. Fix by Jared Minch from NetHack 4.
C343-162 Open Using Magicbane may cause an ungrammatical message.
C343-163 fixed Antholes are mispopulated under some conditions. Fix by Jared Minch from NetHack 4.
C343-164 Open Cancelled nurses may give inappropriate messages.
C343-165 Open 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.
C343-166 Superseded Pits dug in vault guard's corridor don't get removed. See fix for C343-432.
C343-167 Open Length of time swallowed is sometimes calculated incorrectly.
C343-168 Open Shattering a monster's weapon doesn't work right if the weapon is part of a stack of more than one.
C343-169 Open Autopickup fails during a failed untrap attempt.
C343-170 Open 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 Open Silver weapon damage message is sometimes missing when hero is polymorphed.
C343-172 Open Crash could occur when monster uses potion or food to cure stoning or confusion.
C343-173 Open Monster eating lizard corpse is not handled correctly.
C343-174 Open Drum of earthquake gives inappropriate message if hero or monster is in a pit.
C343-175 Open Chatting to hostile prisoners may give an inappropriate message.
C343-176 fixed Disintegration breath hitting equipment carried by monsters is not handled properly; if the monster life-saves the situation is worse; saddles are especially troublesome.
C343-177 Open First false rumor is displayed as gibberish on some platforms.
C343-178 Open Wisdom is mishandled when rumors are used for random graffiti.
C343-179 fixed If a monster is killed by a drawbridge while carrying a potion of acid, the game may panic.
C343-180 Open In an obscure case on special levels, troll corpses may fail to revive and lizard corpses may revive.
C343-181 Open The hero is welcomed to Delphi even if the Oracle was previously angered.
C343-182 Open Putting on the Eyes of the Overworld while blind gives an ungrammatical message.
C343-183 Open Jumping over an already seen trap may give an ungrammatical message.
C343-184 fixed Levitation via worn equipment is not implemented for monsters.
C343-185 Open No message is generated when attempting to name a monster that cannot be named by the player.
C343-186 Open Some messages referring to "priestess" say "priest."
C343-187 Open Meditating monsters continue meditating when affected by something which wakes sleeping monsters.
C343-188 Open Specifying role and/or race and an invalid alignment in NETHACKOPTIONS or config file causes a misleading message.
C343-189 fixed Temple donations and protection lost to gremlin attack interact incorrectly.
C343-190 Open Monsters can hide while trapped or holding the hero.
C343-191 Open When an unseen monster forces a polymorphed hero out of hiding, feedback is insufficient.
C343-192 Open If invocation is performed while hero is trapped, hero remains trapped.
C343-193 Open Polymorphed hero can fall into water once and crawl out twice.
C343-194 Open Saving and restoring a game while punished and swallowed sometimes loses the ball and chain.
C343-195 Open Glass wand thrown and broken in a shop is not charged for.
C343-196 Open Wielded light source may get missed by rust trap.
C343-197 Open Attacking a hidden monster sensed via ongoing monster detection is interrupted inapropropriately.
C343-198 fixed Playing in a 20 or 21 line window can cause the game to crash.
C343-199 fixed The database entry for "monk" has a typo. After comparing this with the source material and finding no significant differences, the only item which I saw which could possibly be considered a typo is the lack of a comma after the last "No", which has been added.
C343-200 Open In the quest, it's possible to accidently skip the locate level e. g. by falling down a hole several levels.
C343-201 Open Phrasing of message when one monster attacks another with stacked weapons is odd.
C343-202 Open Pushing a boulder onto a level teleporter trap could cause repeated messages.
C343-203 Open Hero arriving on a very crowded level may land on a monster causing game state corruption and possibly a crash.
C343-204 Open Hero grabbed or engulfed due to conflict should be released when conflict ends.
C343-205 Open Changes in hallucination state are not reflected properly when also mimicing.
C343-206 Open Divine gifts resulting from #offer are identified when blind.
C343-207 Open Certain items that should never be created in Gehennom can be created there.
C343-208 Open Hero can be blinded while fainted.

C343-236 Open Engraving works in places it shouldn't.
C343-237 fixed The relationship between crossbow use and strength is wrong. The range of firing a crossbow bolt is now independent of strength, and the number of shots you can fire is dependent on strength (with gnomes getting a bonus in this respect); cf. this post by Pat Rankin.

C343-275 fixed If a lit, wielded, candle or potion of oil burns out, the game may crash.
C343-276 fixed If a figuring auto-transforms while wielded or worn, the game may crash.
C343-277 fixed Wooden weapons don't always burn when they should. With the new ways flammable items can be damaged (walking over lava (not just stepping on lava for the first time!) and hitting fire elementals), the author considers this fixed.

C343-279 Open Kicked arrows may get wrong bonuses.

C343-300 Open Amulet of strangulation may kill forms that can't be strangled.

C343-310 Open Applying an unpaid stack of potions of oil forces hero to buy all of them.

C343-317 Open 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 Opening or closing the castle drawbridge using music takes no time.
C343-319 Open Grid bugs can be forced to move diagonally, e. g. by displacing a tame one.

C343-321 Open Hero and monsters can walk through a long worm's tail diagonally.
C343-322 fixed Forced attack on a boulder says "you attack thin air." This was also the case for attacking walls, doors, etc. You now get a "You whack the <target>." message in these cases, with some extra related behaviour.
C343-323 Open Objects dropped as a monster dies don't interact properly with the environment. See also #362.
C343-324 fixed 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.

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

C343-342 Open Potion thrown by monster which hits long worm's tail says it hit its tail.
C343-343 fixed Helm of Opposite alignment gives incorrect piety level. Alignment record is now set to -1 when putting on or removing a helm (this is what happens at the first step of #offering a co-aligned unicorn at a cross-aligned alter, changing the player's alignment permanently).
C343-344 Open NetHack thinks jellyfish have heads.
C343-345 fixed Attempting to remove cursed lenses gives a message with poor grammar. "It is cursed" was displayed instead of "They are cursed"; the latter is now displayed.
C343-346 Open Attempting to put on some items when the item is already wielded or quivered and failing for a variety of reasons gives a message with poor grammar.
C343-347 Open Picking up and wearing an unknown ring while blind sometimes gives out too much information. RGRN discussion

C343-354 Open Probing while engulfed ignores the fact that the hero is in the monster.
C343-355 fixed Archeologists start out at basic skill level in sling. This is a side effect of their touchstone, which is considered sling ammunition.
C343-356 Open Wearing an amulet of restful sleep confuses internal sleep state bookkeeping. Perhaps related is the fact you can cure instrinsic restful sleep (from eating the amulet) by putting on and removing an amulet of restful sleep.
C343-357 Open Rust monsters may chew non-ferrous items.
C343-358 fixed If no co-aligned artifacts are available for gifting when required, gifting fails repeatedly. Not fixed in the conventional sense - if gifting fails to generate an artifact, it will generate a magical weapon instead.
C343-359 Open Setting the fruit name fails if the new name is already known but happens to be not at the end of an internal list.
C343-360 fixed A monster wearing a suit can still put on a shirt. The delay is there, but no extra message is displayed (akin to there being no message for cloaks in this case in vanilla).
C343-361 Open The message "you feel shuddering vibrations" does not always get displayed when it should.
C343-362 fixed Objects dropped during polymorph may be incorrectly polymorphed. Beam-type wands now hit objects before monsters.
C343-363 fixed The case of monsters eating green slime corpses is not handled correctly.
C343-364 Superseded If player's hand slips while naming an object, 'z' is never picked as the new letter. This code is disabled in GruntHack.

C343-370 Open Travel (_) command can get stuck trying to plot a path past an interesting dungeon feature, for example, a trap or fountain.
C343-371 Open 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.
C343-372 Open A fatal explosion can give the player messages in the wrong order if carried items are destroyed.
C343-373 Open 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.
C343-374 Open When polymorphed into a grid bug, attempting to move in an illegal direction is handled ungracefully.
C343-375 Open A mimic posing as a statue is not handled properly.

C343-381 Open Attacking by applying a polearm doesn't scuff engraving under hero.
C343-382 fixed Auto-wielding a polearm may take no time. Occurred when auto-wielding and subsequently cancelling out of the prompt.
C343-383 fixed Applying a bullwhip while hero is at edge of map may cause a panic or crash. Previously, there were no checks that the tile you were applying the bullwhip at was a valid tile.
C343-384 fixed Cutting a level 0 long worm in half may lead to a worm with 0 HP, which may cause a crash. Fix by Jared Minch from NetHack 4.
C343-385 Open D command doesn't handle u choice correctly if only unpaid items are inside containers.

C343-398 Open The game may crash if a wielded potion of polymorph is drunk.
C343-399 fixed Messages referring to a named vault gaurd have grammatical errors. A macro defined in Source:vault.c, g_monnam, was consistently used with a "the" printed in front of it. This "the" is now incorporated into g_monnam, with a couple of edge cases now referring to just "guard".
C343-400 Open Wearing a cloak of displacement identifies it even if hero can't see.
C343-401 Open Wearing an elven cloak identifies it even if hero is already stealthy.
C343-402 Open Putting on a ring of stealth never identifies it.
C343-403 fixed Hero can write a scroll not sufficiently identified. You now must have identified the scroll to be able to write it.
C343-404 Help Writing a scroll can give a badly phrased message if the scroll is known by its appearance. What is the badly phrased message in question?
C343-405 Open Some quest artifacts are too easily affected by stone-to-flesh. The Heart of Ahriman
C343-406 Open One of the coyote names is spelled wrong.

C343-412 Open Unpaid shop items stolen from hero remain on hero's bill.
C343-413 Open While blind, some actions resulting in "Wait! That's a monster!" for a mimic posing as a door do not update the display correctly.
C343-414 Open #untrap of a known trap location with a concealed mimic gives correct message but does not update the display.
C343-415 fixed Mail daemons can be created when populating special levels with demons. Other types of monster that could not otherwise be randomly generated, such as orcs, giants, and woodchucks, were also subject to this; fixed by disabling the ability of the special level generated to ignore the G_NOGEN flag except for classes entirely made up of non-randomly-generated monsters (Kops and eels).
C343-416 fixed Being disintegrated by divine wrath gives an inappropriate message. Instead of "You fry to a crisp" for the wide-angle disintegration beam, it is now "You crumble to dust".
C343-417 Open Polymorphing into a human form may give a message with the wrong gender.
C343-418 Open Weight of non-cursed bag of holding is sometimes off by one. Likely, this refers to multiple stacks of gold in any bag: two stacks of $49 weigh 0, but one stack of $98 weighs 1.
C343-419 Open 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 Open 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.

C343-422 fixed There are inconsistencies in damage applied to objects when encountering lava in different ways.
C343-423 fixed Under some circumstances player can tell if bones file is created. "Your body rises from the dead as <monster>..." is now displayed regardless of creation of bones or not.
C343-424 fixed Unlit candelabrum becomes unlightable if candles have exactly one turn of fuel left and it was applied in the wrong location. Fix courtesy of the original reporter; also related is that the candelabrum penalty applies if on the invocation square and the invocation's already been performed, as with the Book and Bell.
C343-425 Open If a steed's legs are wounded while being ridden and the hero dismounts before the legs heal, the hero's dexterity will stay reduced. (original report)

C343-431 Help Killing a vault guard results in a message about "dropping minvent." How can this message be generated?
C343-432 fixed In a vault corridor: some traps could be left lying around. All traps in a corridor are now removed when the corridor disappears.
C343-433 fixed In a vault corridor: you can end up with lighted rock. The lit state of a tile is now reset when it resolidifies.
C343-434 Open In a vault corridor: when blind, you can be stuck and not be told why.
C343-435 fixed In a vault corridor: various kinds of problems may result from having an iron ball. It's unknown exactly what symptoms the bug refers to, but the ball and chain handling code for resealing corridors has been changed such that the ball and chain are replaced at your position when the corridor disappears, as opposed to stopping at the point where the iron ball is placed.
C343-436 fixed Hero can levitate and fly where it makes no sense. Listed as fixed on the assumption that this refers to the Plane of Water.
C343-437 Open Gremlins sometimes don't respond properly to light.
C343-438 fixed Typo "gold piecess" may occur when selling items in a container. To trigger this bug in unpatched variants, one needs to find a container the shopkeeper owns, fill it with enough items that the shopkeeper can't afford to pay for the items inside, then drop the bag to sell the contents.
C343-439 Open Running NetHack in a terminal window with more than 255 rows or columns produces display errors.
C343-440 Open If the game panics with the hero underwater, the hero may be restored on top of the water.
C343-441 fixed Autosearching while blind doesn't update the map when it should.
C343-442 fixed Drain life shouldn't override drain resistance of objects. Artifacts granting drain resistance (Excalibur, Stormbringer) could be drained by drain life; this is no longer the case (also applies to GruntHack's thirsty / drain resistance objects).

Spoiler core bugs

Name Fixed in GruntHack Description
SC342-3 fixed Hangup can be used to cheat.
SC343-1 fixed Monsters that can't blow can still use a whistle.
SC343-2 fixed If you are poison resistant, potions of sickness can only kill you if they are blessed. Previously, they dealt 1HP damage if not a healer without checking for poison resistance. The damage is now not dealt if you have poison resistance.
SC343-3 fixed Water walking boots are not handled properly on lava. If the player steps onto lava with non-fireproof water walking boots and can survive the lava burning damage, they were left standing on the lava without boots. Now the boots are destroyed immediately if they are not fireproof, leaving the player to fall into the lava.
SC343-4 Open Reviving corpses or reanimating statues in a shop does not get charged correctly.
SC343-5 Open Breaking container contents in a shop doesn't always charge for them.
SC343-6 Open Stealing a stack of items from a shop sometimes results in only being charged for one.
SC343-7 Open Zapping an unknown wand while blind sometimes gives out too much information.
SC343-8 fixed Re-animating a statue containing gold produces too much gold. Monster's gold is now cleared before creating the statue (the value is saved to create the object inside the statue), so that the gold object doesn't stack with the monster's carried gold.
SC343-9 Open Medusa corpse from a level file behaves incorrectly.
SC343-10 fixed Player can raise HP and Pw by dancing with vampires. The polyself bug; addressed by using the same formulas to adjust HP/Pw from polyself as when changing levels normally, with up to a +/- 10 adjustment (carried over from original behaviour). It's still possible to gain HP; it's just much, much more tedious (and in the long run your HP will come out even anyway).
SC343-11 fixed It's possible to easily find the identity of a high priest on the Astral plane.
SC343-12 fixed Hero using telepathy can abuse Call on the Astral Plane.
SC343-13 fixed While blind and levitating, too much information may be presented. Fixes are primarily in relation to dungeon features and objects on floor.
SC343-14 Help Shopkeepers and priests may be teleported out of their shop or temple too easily. What's the intended behaviour here?
SC343-15 fixed Nurses are not stoned by hero polymorphed into cockatrice. Refers to their healing attack, which also didn't take other forms of passive damage when used against a polymorphed player.q
SC343-16 fixed Gelatinous cubes can engulf Rider corpses.
SC343-17 fixed Stethoscope may unhide hidden mimic.
SC343-18 Help Escaping from lava can leave hero outside of time. Possibly fixed by the fix for C343-231, but without knowing how to abuse the bug, it can't be tested.
SC343-19 Not a bug Monsters seeking the Amulet attack temple priests to get it. The behaviour of covetous monsters has changed such that it's intended that they will attack anything between it and the Amulet where applicable.
SC343-20 fixed Hangup save while picking up gold in a shop may duplicate the gold.
SC343-21 Open Accounting is incorrect for containers dropped in a shop that does not sell them.
SC343-22 fixed The travel command allows grid bugs to move one step diagonally.
