Name	Status	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.	This is possible loading bones levels created with earlier versions.

C341-10	Fixed	Fruit names ending in "us" are incorrectly considered plural.
C341-18	Fixed	ki-rins and couatls can wear (and may have) armor.	Shields, boots, gloves, and (non-metallic for ki-rin) helmets.

C342-13	Fixed	Hangup can cause loss of objects being moved internally.
C342-16	Fixed	If you self-genocide while polymorphed, the death message makes no sense.
C342-19	Fixed	Things that can kill you in the future (like stoning) can cause messages to show up out of order.
C342-22	Fixed	Monsters can hide under cockatrice corpses without getting stoned.	Also: "You sit on the cockatrice corpse. It is not very comfortable."
C342-31	Open	You can get a message telling you a monster wields a weapon it already was wielding.
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.

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.	But you can't pick it up or enter the pit with >, which is arguably the real bug.
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.	You have to fall into a pit, which xorns can't. Workaround: levitate and apply a bullwhip down.
C343-17	fixed	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	fixed	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	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.

C343-22	Fixed	You can untrap a monster in a pit while levitating.
C343-23	Help	Dungeon collapses after vault guard fails to lead you out.

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.
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	fixed	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	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	Open	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	fixed	Restoring a game where the character is wielding Sting may result in temporary display errors during the restore process.
C343-40	fixed	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	fixed	A rolling boulder falling into a pit you can't see only makes a sound if the hero is blind.
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.
C343-44	fixed	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	fixed	Dropping the corpse of a unique monster without a personal name down the stairs gives a badly formed response.
C343-46	fixed	Breaking up a boulder or statue can result in pieces that are described incorrectly.
C343-47	fixed	Monster and hero have different odds to err when throwing a greased weapon.
C343-48	fixed	Killing your pet doesn't get you any experience when it should.
C343-49	fixed	The boulder does not show up in a bones file caused by death by rolling boulder.
C343-50	fixed	A sleeping steed may answer a #chat.
C343-51	fixed	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	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	fixed	If a shopkeeper is trapped adjacent to the door, the game may get confused and issue impossible or panic messages.
C343-54	fixed	"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	"Ulch" messages have inconsistent capitalization.
C343-56	fixed	Gas spores can't attack while hero is praying.
C343-57	fixed	#enhance command descriptions in Guidebook and game do not match.
C343-58	fixed	#conduct command description grammar is poor
C343-59	fixed	Engulfer stoned swallowing hero polymorphed to cockatrice causes incorrect screen display. If hero has ball & chain, game can panic.

C343-61	fixed	Using a WIZKIT including the quest artifact will crash the game at startup.
C343-62	fixed	Riding into a magic portal gives an extra, useless message.
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.
C343-65	fixed	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	fixed	Co-aligned unicorns in a bones file may be hostile.
C343-67	fixed	Finding a statue when searching while blind doesn't update map.
C343-68	fixed	Incorrect message may be given when a spellcasting monster summons other monsters.
C343-69	fixed	Attempting to add more candles than needed to a candelabrum with at least one candle gives an incorrect message.
C343-70	fixed	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	Fixed	When swapping places with a pet pushes it into a trap, the messages are out of order.
C343-72	Fixed	You get confusing messages when you stop levitating while on a flying steed.
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 lists claws as a horse’s manipulatory appendages.
C343-78	fixed	Digging in an existing hole charges you for the time it takes to dig the whole hole.
C343-79	fixed	"Mr." or "Ms." may show up in front of names when it should not.

C343-107	fixed	Killing your own steed never leaves a corpse.

C343-112	fixed	Hero and monster afflicted with lycanthropy are treated differently.
C343-113	fixed	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.
C343-115	fixed	Sleeping or paralyzed unicorns can catch gems.
C343-116	fixed	Grammar error in messages related to choking on gold.
C343-117	Fixed	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	fixed	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	Fixed	Eating various brains which should have special handling, don't.

C343-128	Fixed	Feedback for gas spore explosion when hallucinating could be improved.
C343-129	Fixed	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	fixed	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.
C343-131	fixed	Message has poor grammar if hero killed when stealing cockatrice corpse from a monster.
C343-132	fixed	Message when death caused by kicking an object can be too verbose.

C343-148	Fixed	Changing locations while asleep lets you see objects or read engravings.
C343-149	Fixed	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 blessed scroll of amnesia.
C343-150	fixed	Gender and/or size of some quest quest leaders and nemeses are wrong.
C343-151	fixed	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.

C343-169	Fixed	Autopickup fails during a failed untrap attempt.

C343-188	fixed	Specifying role and/or race and an invalid alignment in NETHACKOPTIONS or config file causes a misleading message.

C343-217	Fixed	Missile which kills engulfer is temporarily lost when hero is expelled.
C343-218	fixed	Applying a wielded cream pie can crash the game. This generalizes to wielded objects being destroyed.
C343-219	fixed	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	Fixed	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	Fixed	Jabberwocks do not always wake up when they should.
C343-222	Fixed	It's possible to end up wielding a cockatrice corpse when no longer polymorphed.

C343-230	fixed	Drawbridges act differently depending on which direction they are pointing.
C343-231	fixed	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	fixed	Hero can be slimed while in lava.
C343-233	fixed	Hero polymorphed into Quantum Mechanic may get erroneous messages about disappearing monsters.
C343-234	Fixed	Sacrifice on an altar can have unintended consequences. Perhaps this refers to the fact the corpse of a former pet does not vanish.

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

Bugs not mentioned on the DevTeam's website

Name	Status	Description
		The hero can teleport on a non-teleport level: Get engulfed by a tame engulfer using conflict, end conflict, apply a magic whistle.
		It is impossible to paste (e. g. "ElberethElbereth") into the windows tiles build. This works on OS X, however.
		The game sometimes behaves as if a series of spurious non-attacking movement commands were typed after #looting a container.
		Confused #looting a throne does not destroy it.
		The "highlight_pet" option does not work on monsters only seen due to the monster detection spell.
		Polymorphing a cloaked pet mimic (by whistling it onto a polytrap) does not unhide it, even if it turns into a non-mimic.
