[X] Random client crash after logging into SMP.--Inertia 01:08, 7 September 2012 (UTC)

[!] [SP] Minecraft will STILL fail to save the world properly. A bug noted by many in the 1.3.1 update, still present in 1.3.2 and the current snapshots ocurring in some systems. This bug leads to progress made in worlds go to waste. --Manuelschi 18:13, 7 September 2012 (UTC)

[!!] When creating a zoomed-out map, if instead of using 8 paper you use 16+ paper and place the output in the crafting grid, the game will crash. Here is the crash report:

[!!] My client crashes when I try to load or create any of my worlds. It has done this thing with each of the post 1.3 snapshots, and I use a clean jar each time I install a snapshot. IGN-marsrex15

[!] [MP] My friends and are unable to connect to my server. We all get the same crash report. The server only shows as if we lost connection, but never says anyone connected.


EDIT: We have figured out that we are able to connect to the server, but we must wait around 15 to 30 minutes after it is started to connect.

RickNovile 02:37, 9 September 2012 (UTC)

[!!] Server randomly crashed after about 24 hours of uptime. No obvious indication as to why. After it generated the crash report, the server responded to "stop" command at the console but not to any socket call. --Inertia 02:37, 12 September 2012 (UTC)

[!!] Similar to the above crash, on the same server. --Inertia 04:58, 13 September 2012 (UTC)


[A] The Minecraft launcher and title bar of Minecraft are pixelated on retina displays running OSX (and possibly Windows).

  • This is supposed to happen. --DevEd 11:17, 11 September 2012 (UTC)

[A] Sometimes villages spawn with split doors,one in the front of the door way with no top,one in back with no bottom.12w36a only.




[X] The pillar descent bug still isn't fixed! Etho demonstrates -- Featherwinglove 20:17, 11 September 2012 (UTC)

[!] Right after being killed and respawning, what looks like parts of a wither started floating out of the ground and flying around. --YouEatPig 19:36, 8 September 2012 (UTC)

[!] Sometimes, the game doesn't save blocks placed by the player

[!] it seems that snow golems are broken. I was testing this out on a lan server and when i made the snow golem it did not make any snow. when i reloged it was gone. it could not be killed or interacted with.-fallonsky

[!] There seems to be a lighting/graphical bug and a mob collision bug. Minecarts have a graphical glitch (one side is black from absence of light), boats continue moving on the ground after being spawned while the player is moving forward. When spawned onto ground, boats often phase/noclip into the ground and disappear from sight or have the black texture lighting glitch. This may be related to the pig riding bug (pig noclipping into the ground while being controlled). (Bugs observed while in creative with cheats enabled). --M0rphzone 03:19, 7 September 2012 (UTC)

Update: Riding pigs in minecarts makes things even worse. The pig seems to be attempting to spawn/exit the minecart, and it "teleports" a few blocks away from the minecart (similar to players exiting carts/boats), but remains stuck in the minecart with the image of the pig constantly shifting outside and then being pulled back inside. If the rails are broken while the cart is in motion, the cart seems to perpetually move in the direction that it was last moving to when it exited the rail. The cart continues to move on the ground (no rails), and only stops once it hits a solid block. --M0rphzone 03:40, 7 September 2012 (UTC)
  • I've noticed that riding a pig in a minecart speeds it up without the need for powered rails, but I haven't tested on the ground with out any rails. --Keithicus420 14:47, 8 September 2012 (UTC)

[X] If you get out of a minecart on a track next to a wall of iron bars or glass panes, you can end up on the other side of the wall depending on which side of the track the wall is. --Thorny 02:02, 7 September 2012 (UTC)

  • same goes for cobblestone walls and (maybe) fences

[X] When riding a pig, the character's body doesn't rotate, the character's head can turn 360 degrees. --conscripta

[X] [MP] I am not sure of the exact conditions needed, but many pressure plates of mine are not working. I step on them, normally, while falling, falling by teleportation .etc I can only step on it once and any other time afterwards the pressure does not power at all. The noise is also not created. RickNovile 19:28, 9 September 2012 (UTC)


[A!] Lightning can cause MAJOR fire damage all over the map in Hard. In multiplayer especially, this seems exceptionally unfair to players, who weren't even online to be able to do anything about their burning homes and constructs. a different way to control fire spread, perhaps specifically for Multiplayer, would be very much appreciated.
As of right now, my own server is still on hard, but fire does not tick, as per the recent Gamerules. Lighting however has still littered the landscape with fire. I had to rollback three times to fix the world causing carnage. --Kizzycocoa 15:39, 6 September 2012 (UTC)

[A] In Adventure mode a player can break an item frame and steal it and the item. They can also rotate the item in the frame.

  • Certainly not a major annoyance, please check with the rules at the top of the page. Perhaps this is intended. --Keithicus420 14:42, 8 September 2012 (UTC)
  • In Adventure mode, you can interact with blocks (flick levers, etc.), so being able to change the orientation of the item in the item frame does not seem to be incorrect behavior. --banana478 15:11, 8 September 2012 (UTC)
  • I'm sorry apparently this is intended though it makes literally no sense based on the definition of Adventure mode. I hope this topic is debated by the developers. (I figure it's intended because you can also break paintings the same way. Sorry, wipe this if it's truly irrelevant.). --Acidnine 15:03, 10 September 2012 (UTC)
  • In my opinion, adventure mode is that to which you can set all joining players to have full control over their being in your map. Flicking a lever doesn't mess up anything (unless it's for decorational purpose only), but knocking down paintings, rotating items in item frames and taking down item frames doesn't seem like something that should be doable by the "audience" (people in adventure mode). If this actually is intended behavior, I don't know. To me, it seems like an oversight. 17:58, 10 September 2012 (UTC)

[A] It is not possible to place Redstone underneath an upside down slab of any kind.

  • Of course not. An upside down slab is occupying the entire block, just as redstone dust occupies the entire block it's in. Downgraded. --Keithicus420 14:42, 8 September 2012 (UTC)

[A] When flying in creative mode with your head pushed up against a block just over flowing water, the seafloor looks as if you weren't looking through water, and this effect is even more noticeable with Night Vision. --banana478 15:24, 8 September 2012




[!] Timing on NOT gates (redstone torches) seems to be broken. I would expect them to act as a one tick inverting repeater but they seem to require a three tick pulse to activate and then only emit a two tick pulse. This effects any circuit that depends on timing, pulse length, or short pulses. A full explanation of the problem can be found here: Video The video was recorded in V1.3 but the bug is the same in 12w36a --Innovate.Invent 05:49, 7 September 2012 (UTC)

[!] End Portals can be destroyed by Withers. The list of blocks that Withers can't break should include any block with a negative hardness value. TorchicBlaziken 00:19, 7 September 2012 (UTC)

[X] Bug existing since 12w32a, some aspect of the bug have been fixed, but it is still present : Some blocks can be seen through the "light ray" block when you place a lot of Beacon Block close together. Not sure if this should be in the "graphical bugs" section or here... List of the blocks visible : Water, Ice, Nether Portal, Enchantment Table (book only), Screenshot 12w36a ~Geneosis 13:30, 6 September 2012 (UTC)

  • it is probably because they have 3d textures (not just a 6 sided block) or transparency. same happens when you look through a water stream, except opposite. you cant see water or ice or nether portals.

[X] The books on Enchantment Table are blurry. Proven by Screenshot. jozzamay 15:17, 6 September 2012 (CET)

[X] Most paintings over 2x2 blocks seem to fall off the walls after loading. You can't seem to replace them, either. I've noticed this since 12w34a.

  • I can't place paintings that large at all. They always come out 1x1 or 1x2, and all my other sized paintings flew off the walls when I first loaded 12w34a. --Pteprocks 01:58, 7 September 2012 (UTC)

[X] If you die by multiple zombies, they can pick up the item and upon their death drop multiple, duplication bug.

[X] Tree leaves will delete stairs when a tree grows if the stairs are in the area of where the leaves are placed. This may include any block in which light transparency/flow through is allowed. I've found forum posts claiming this has existed for quite some time and at least as far back as 1.7. Screenshot

[X] For the wooden button, if you fire an arrow on the bottom half of the block a wooden button is attached to, it triggers the button, whereas doing the same for the top does not work. Could this have something to do with that old minecraft 1.2.5 bug where arrows zoomed to the top of a block?

  • I don't know what causes that, but to me it seems like a bug. Upgraded. 18:11, 10 September 2012 (UTC)

[X] The Beacon block does not work, when it is placed at heightlevel 1. No ray shows up and the effects are not selectable too. When the block is placed at level 2 or higher everything works fine. Screenshot


[A!] If somebody tries to create a Wither on Peaceful mode, it will quickly disappear, like other monsters, but this makes the player loose the blocks used to make it. --X 15:50, 8 September 2012

[A] The Beacon Block can be harvested with bare hands. --M1n3r2011 11:31, 7 September 2012 (UTC)

[A] Repeat of older bug, plus new info: Glass panes join to leaves, which is illogical in my view, but won't join to step blocks, which is a pain, especially when you're trying to put windows in a roof. Glass panes also join to bookshelves - also illogical. I don't think glass should join to dirt, sand or gravel either. How would you get a seal on such a join? Fences, OTOH, could be dug into the sand (or whatever) and could reasonably expect to find themselves placed next to sand, dirt etc. under normal circumstances. It seems that what joins to what needs to be hand-tweaked slightly; a simple 'joins to any full-sized block, transparent or not' algorithm (which is what glass currently seems to do) produces some odd results. -- 01:34, 7 September 2012 (UTC)

  • This isn't a bug, downgrading. If in your opinion the game shouldn't do something it is, that's an annoyance. I agree that it could be an inconvenience when putting glass next to steps, but it's the way the game is, and everything can't just be changed for what you feel glass should and shouldn't join to. Bookcases are whole, opaque blocks, so there's really no reason for it not to connect to them. --Keithicus420 14:53, 8 September 2012 (UTC)
  • I disagree with your downgrading this, for reasons given on the talk page -- 17:51, 8 September 2012 (UTC)

[A] Cobblestone walls do not connect to fences. That would be esthetically cool to make them do it (like nether fences to fences), for those who likes mixed materials walls. Anadeidra, 9 September 2012

[A] Cobblestone walls do not nicely connect on the up direction with themselves. A two blocs high cobblestone wall is discontinuous on the vertical direction, which isn't nice at all. Even if it was intentional (to forced us not to do two blocs high cobblestone walls, so as to keep the the "cubic" aspect of minecraft), the player is sometimes forced to do so (when he wants to enclose non-flat spaces from mobs). Anadeidra, 9 September 2012




[!] Item duplication issue exists. when a minecart with chest enters a portal with items, the items in the chest at the other end can be duplicated infinitely. --Kizzycocoa 12:13, 10 September 2012 (UTC)

[X] Placing paintings still only results in 1x1 and 1x2 paintings regardless of space available. --Pteprocks 19:18, 6 September 2012 (UTC)

[X] Duplication bug: Send a Minecart Chest with an item through an End Portal. The Minecart Chest will break and drop its items. If the player goes through the portal, The Minecart chest appears in the End, and has all of its items still in it. The items in the chest can somehow be duplicated infinitely, and in the case of blocks, can be placed and crafted. In some cases, tools will instantly break. It is much easier to explain with a video, so here is a link: http://www.youtube.com/watch?v=Br4N-tZIFP8 --Lapppy 02:17, 7 September 2012 (UTC)

[X] Mousing over a really old map with F3+H on causes the game to crash.

  • Happens consistently for me when trying to get my nether map that is from when maps were first added to the game out of a chest.
  • This is a bug, not an annoyance, since it actually causes a game crash. Moved. --WolfieMario 21:46, 7 September 2012 (UTC)

[X] Duplication bug: When surrounding more than one map with paper, the crafting output slot presents as many maps as are in the input slot. When these maps are taken from the output slot, only one map is removed from the input slot. For example, if you attempt to zoom a stack of 64 maps using the crafting recipe, you will get 64 zoomed maps, and keep 63 of the original map, at the cost of 8 paper. Thus you essentially almost double the amount of maps you have. --WolfieMario 21:46, 7 September 2012 (UTC)

[X] Drinking a potion of invisibility while on the back of a pig causes the player to remain visible until dismounting. Inversely, if you are invisible and drink milk, the player remains invisible (until dismounting) --Cuulcars 22:33, 7 September 2012 (UTC)

[X] The enchantment effect 'Unbreakable' on tools seems to cause a weird phenomenon. When the tool breaks the usual 'break' sound sometimes cannot be heard. In such cases the item seems to be gone from the inventory at first (both the players hand and the tools inventory slot is empty), but upon clicking the now seemingly empty slot, or placing something else there, will pick up the previously broken item (with the minimal possible durability left). The 'revived' tool can be used again, and it can break several times before it breaks for good (when that happens, the 'break' sound is played properly). I think the item is saved this way when the 'Unbreakable' effect kicks in on the last bit of durability. -- 13:07, 8 September 2012 (UTC)

[X] If the player attempts to have a mob such as a zombie wear a head, they will simply hold the item. The real problem occurs if the mob is forced to wear a head. Instead of an expected result, a large plane with soul sand texture will be jutting from inside the mob. I assume this to be the head in a glitched form, as when broken they have a soul sand particle effect. Example:

[X] [?] Maps cannot map The End, despite there being no reason as to why this is disallowed.

[A] When a map is placed on an item frame, the location of the frame is denoted with a green cursor if the frame is within the mapped region.

Perhaps a green circle should be added to reduce confusion? --WolfieMario 21:46, 7 September 2012 (UTC)

World Generator[]


[!] Nether Fortresses can spontaneously lose their spawning capability of special mobs. We had a fortress do well for days. today, I log onto our multiplayer server, and no blazes, so skeletons and no wither skeletons! a pretty large bug, considering this can demote an entire fortress.--Kizzycocoa 11:14, 10 September 2012 (UTC)

  • I've noticed that fortresses in general have a rather underpowered spawning capability. I may be wrong on this, but it seems nether biome spawns are evaluated in a chunk before fortress spawns, making all fortress mobs dramatically rarer even within a fortress. Also, if fortress spawn locations shuffle during updates, that's a major annoyance (if not a downright bug), as fortress locations are not saved to a map (this is similar to how biomes previously shuffled, but are now stored). It may be better to give fortresses a technical biome, or at the very least, evaluate them with the same precedence as a biome. --WolfieMario 18:59, 10 September 2012 (UTC)
  • This happens when the world is closed and reopened. The current version does not seem to save the data which are used to determine the location of the Nether Fortresses in a retrievable manner. This video contains more information: http://www.youtube.com/watch?v=KlyGqqHIIVg --KaboPC 19:12, 10 September 2012 (UTC)

[X] Villagers often can't get back into their own houses. This image is a mild example; my record so far (and this excludes chasm villages) is a church with an eleven block drop in front of the door. Can we have a bit more terraforming for villages, so that their paths aren't quite so higgledy-piggledy (and/or underwater), there aren't villager-swallowing gaping pits in the middle of the high street and house doors aren't inaccessible? I appreciate this is a well-known problem, but I feel it's overdue some attention. --Simons Mith[] 23:30, 7 September 2012 (UTC)


[X] Older Nether fortresses do not spawn Wither Skeletons.

  • My old Nether fortress had no Wither Skeletons at the beginning as well, but after some time they spawned normally. -- 22:17, 10 September 2012 (UTC)





[!!] When riding a pig if you enter a End Portal then the client will crash. --Zzzaaaccc13 17:05, 6 September 2012

  • Could you post a crash report? --Coupon22 22:38, 6 September 2012 (UTC)

[!] When in a village, Iron Golems randomly attack you. I didn't hit it or a villager. Here's some info The village is in a desert. The world was generated in one of the 1.3 snapshots (one with pyramids in it) There's a pyramid nearby. I expanded the village. There are two Golems in the village: one will suddenly hate me, and the other one is still neutral.

Please fix this, I'm hiding in my house waiting for this bug to be fixed. UPDATE: The golem forgave me.

[X] Unable to breed pigs with wheat. They will not eat it and do not follow you around. Cows and sheep are fine.-Porrohman

  • Could you post a picture? --Coupon22 22:38, 6 September 2012 (UTC)

[X] Pigs may glitch/noclip into blocks (and flash black) while being ridden. May have been caused by multiple right-clicks while using the carrot on a stick, or from the pig entering water and exiting. --M0rphzone 03:00, 7 September 2012 (UTC)

[X] Pigs do not respond to carrots on a stick once they enter water (can't control them while in water). --M0rphzone 03:04, 7 September 2012 (UTC)

[X] The head of the Wither Skeleton isn't included in their hitbox. 10:05, 7 September 2012 (UTC)

[X] When riding a pig it rapidly blinks. --Trinistr 10:43, 7 September 2012 (UTC)

[X] Zombies are not affected by splash potions of weakness or healing (and some other splash potion effects). This means Villager zombies cannot be healed using the potion of weakness, golden apple technique. -- 20:28, 7 September 2012 (UTC)

[X] Skeletons can spawn in Nether Fortresses. I believe this has to do with the fact that both types of Skeleton share an Entity ID, and so the game spawns a Skeleton instead of a Wither Skeleton. 19:08, 8 September 2012 (UTC)

[X] If you are playing in an earlier generated world (1.2 in my case) the nether fortresses you have already explored do not appear to have any Wither Skeletons.

[X] Wither Skeletons don't appear to respawn once you have killed them. I discovered a new Nether Fortress in my world, explored it, and killed multiple skeletons and wither skeletons. Searched around the same fortress for an additional hour without encountering any more wither skeletons.

  • I observed the same thing - I had to travel to a newly generated Nether Fortress to obtain some heads ;), saw and kill a few Wither Skeletons. After I returned home into Overworld to get Looting III sword to make it easier, neither Wither skeletons nor Blazes were to be seen in the new fortress. Also, maybe closing and reopening the world was involved. To think about it, I have never seen not-from-spawner Blaze prior to this moment. So this bug is there maybe a very long time. --jenceslav


[A] When you breed pigs with carrots, the hearts over their heads don't appear.

[A] On Hard mode, zombies always (100%) turn villagers into more zombies. On easier mode they may just kill them. But that means a village is in greater danger of becoming depopulated on easier game modes, which seems like a perverse result. On the hardest mode, with work you could theoretically trap all the zombified villagers and cure them (repeatedly) every time they get zombified, thus maintaining the village population. -- 15:03, 6 September 2012 (UTC)

  • I believe this is intended behaviour. --Kizzycocoa 15:40, 6 September 2012 (UTC)
  • It makes sense in that zombies can only break down doors on hard difficulty. On easy/normal difficulty only a few villagers would die during a zombie siege - if any at all. On hard difficulty there's a good chance they'll all get killed. 20:51, 6 September 2012 (UTC)

[A] Wolves do not listen you if you tamed them when playing online/offline then playing offline/online. (Perhaps make an exception for localhost games?) 03:52, 7 September 2012 (UTC)

  • This happens because the wolf store the owner of it by recording the tamer's username. Online: stored with your username/ Offline: stored as "Player". Yet it's still an annoyance if not a bug. --Manuelschi 19:57, 7 September 2012 (UTC)

[A] Wither Skeleton Skulls are the only obtainable head in survival mode. This is a real shame, as the item has some nice building potential, and it doesn't make sense that ordinary skeletons can't drop their skull. While there may not be a reasonable way for the human head to be added to survival, perhaps skeletons, zombies, and creepers can drop their heads at the same rate as wither skeletons? --WolfieMario 21:53, 7 September 2012 (UTC)

[A] Zombies will not equip any of the given Heads found within the game, nor will they Equip pumpkins. Not sure if this is a Bug or not, but I do find it annoying. --NomFRENCHTOAST 13:54, 8 September 2012 (UTC)

[A] A Whither will still attack you if you have used a potion of Invisibility on yourself - Not a bug, intended behavior.

  • This is the post that was in the bugs section, but it says intended behavior, so I corrected the tag and moved it here. --Keithicus420 15:06, 8 September 2012 (UTC)

[A] When you are controlling a pig, it doesn't jump over blocks.--League 19:31, 6 September 2012 (UTC)

  • I don't think that is a bug, so I downgraded it to annoyance. Riding a pig doesn't deplete your hunger bar at all, and if the pig could jump over blocks you could essentially travel anywhere you want with no food. 20:51, 6 September 2012 (UTC)
  • That makes no sense, there are already boats and minecarts which don't deplete hunger, and by the time you get far enough along to be able to ride a pig, you probably won't have any shortage of food anyway-- the purpose of being able to ride a pig is to get to places faster. It's kind of pointless having to dismount your pig, lead him up a hill, and get back on to keep going. Therefore, since I highly doubt it's intended behavior, upgrading back to bug. --Pteprocks 01:53, 7 September 2012 (UTC)
  • Vote to downgrade to annoyance. Mojang is working on this, and this is not a bug: Just simply not worked on. -- 14:25, 7 September 2012 (UTC)
  • Vote to downgrade to annoyance as well. You can place either half slabs or stairs where the pig will travel and it will go uphill. 06:39, 8 September 2012 (UTC)
  • Multiple votes for downgrade, so I corrected. Controlling pigs is brand new to the game, so please be patient while the Mojangstas work out the kinks. --Keithicus420 15:06, 8 September 2012 (UTC)

[A] Enchanted tools/armor placed in item frames do not have the enchanted auora graphic effect. (building a custome world with custom villager shops, annoying because I'm using item frames to show what the shops sell, and the pre-enchanted items shop seems to just be another tool shop.)

[A] When the Ender Dragon's feet touch a material that it cant break, the walking sound is played. 07:09, 8 September 2012 (UTC)




[X] [MP] The "Add server" and "Edit" screens on the multiplayer server list don't accept IPv6 addresses. "Direct Connect" works fine, as does manually editing servers.dat, so it's just the front-end validation code that's a problem. (To be correct, it should treat the entire thing as an address if there's more than one :, unless of the form [2001:470:db8:42::1]:25565, in which case the contents of the square brackets are the address.) -- Dagger 19:26, 9 September 2012 (UTC)



In-Game Interfaces/HUD[]



[A!] Lack of in-game feedback about the current difficulty level is annoying. I spent some time in a game wondering why no mobs were spawning, then eventually realised that I'd set the difficulty to Peaceful while playing another world. Just an indicator of the current difficulty setting on the game load screen would be sufficient. Grrr. -- 19:50, 6 September 2012 (UTC)

  • Actually, changed my mind and upgraded to a bug, because changing the difficulty setting in one world shouldn't affect the difficulty in another, separate world.
  • I completely agree with you. It doesn't make much sense and it is annoying. Nevertheless, it is not a bug, and thus it should not be marked as one. On a quite similar note, it would be nice if stats and achievements were saved on a per-world basis as well. This issue is the one reason I don't want to ever make a creative world - the stats get completely messed up, and if I forget to set the difficulty back to what it was I may end up doing a ton of caving before I realise it was on peaceful all along and I feel like a cheater! Very, very annoying. Changed to major annoyance. 21:05, 6 September 2012 (UTC)
  • I cannot think of another computer game where changing the difficulty in one saved game affects other saved games. Nor can I think of any games with a global difficulty setting that affects all saved games. Given this, how can Minecraft's behaviour (different from everything else I can think of) be anything other than a bug? I'm not changing the rating back just yet, but misusing the Annoyances tag for things that really ought to be classed as bugs is not very helpful to the Mojang devs. -- 19:51, 8 September 2012 (UTC)
