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.	This is possible loading bones levels created with earlier versions (NetHack 3.4.0 according to Bugs in NetHack 4).
C341-4	Unknown		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	Unknown		Skilled or expert caster of fireball/cone of cold can't target a monster known only by infravision or ESP.
C341-10	Unknown		Fruit names ending in "us" are incorrectly considered plural.
C341-18	Unknown		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	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.
C342-19	Unknown		Things that can kill you in the future (like stoning) can cause messages to show up out of order.
C342-22	Unknown		Monsters can hide under cockatrice corpses without getting stoned.	Also: "You sit on the cockatrice corpse. It is not very comfortable."
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	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.
C342-50	Unknown		If you're hiding on the ceiling and try to #sit, you automatically unhide.
C342-51	Unknown		The game thinks trappers hide on the ceiling.
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.
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	Unknown		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.

C343-6	Unknown		You can #sit on an object at the bottom of a pit that you are not in.
C343-7	Unknown		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.
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.
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".
C343-14	Fixed	GruntHack	The initial and any tombstone message resulting from eating an identified artifact is gramatically incorrect.
C343-15	Unknown		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+[1]	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.
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.	This doesn't matter - mostly.
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.
C343-24	Unknown		Documented default for option "null" is "off"; default is actually "on".
C343-25	Unknown		You can trip over a cockatrice corpse safely.
C343-26	Unknown		A frozen swamp may be called a moat.
C343-27	Unknown		Kicked objects do not slide properly on air or water levels.
C343-28	Unknown		There are several places that can't tell the diffence between a "hat" and a "helmet."
C343-29	Unknown		When taking things out of a bag of holding, messages may say "lifting" instead of "removing."
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.
C343-32	Unknown		When blind and levitating, the hero can still discover stairs.
C343-33	Unknown		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.)
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.
C343-41	Unknown		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	Unknown		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	Unknown		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	Unknown		Monster and hero have different odds to err when throwing a greased weapon.
C343-48	Unknown		Killing your pet doesn't get you any experience when it should.
C343-49	Unknown		The boulder does not show up in a bones file caused by death by rolling boulder.
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	Unknown		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	Unknown		If a shopkeeper is trapped adjacent to the door, the game may get confused and issue impossible or panic messages.
C343-54	Unknown		"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	Unknown		Gas spores can't attack while hero is praying.
C343-57	Unknown		#enhance command descriptions in Guidebook and game do not match.
C343-58	Unknown		#conduct command description grammar is poor
C343-59	Unknown		Engulfer stoned swallowing hero polymorphed to cockatrice causes incorrect screen display. If hero has ball & chain, game can panic.
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.
C343-63	Unknown		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	Unknown		A black light leaves an hallucinated corpse while exploding.
C343-65	Unknown		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	Unknown		Co-aligned unicorns in a bones file may be hostile.
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.
C343-69	Unknown		Attempting to add more candles than needed to a candelabrum with at least one candle gives an incorrect message.
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	Unknown		When swapping places with a pet pushes it into a trap, the messages are out of order.
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.
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.
C343-77	Unknown		Some messages referring to monsters that look like horses refer to claws.	polyself.c lists claws as a horse’s manipulatory appendages.
C343-78	Unknown		Digging in an existing hole charges you for the time it takes to dig the whole hole.
C343-79	Unknown		"Mr." or "Ms." may show up in front of names
