Crashing/system
Bugs !! When a player takes a map from a Stronghold's chest, the game crashes

x If you open the game via Terminal or the command prompt and attempt to load/create a world, it always displays the world loading at "0%", meaning that there is no way to track world loading progress, almost making me believe I couldn't load worlds. --Wormy14 22:04, 4 October 2012 (UTC)

Annoyances The client download loaded into 12w40a seems to be 12w39b. It doesn't show the 12w40a in the bottom right, and world generation is still long.
 * Did you completely replace the minecraft.jar? I downloaded 12w40a and it works exactly as it should. -Debugman18
 * It seems to work normally for me, no problems there. What is really funny is that last period 12w40a did not exist, so i was stuck for five minutes generating a world with 12w39b.

Gameplay
Bugs

mp Items not shown exactly where they are. The client seems to be moving items where it expects the items to be. Sometimes on servers I program items to be inside glass blocks, but the client shows the items pushed out of the glass blocks when they are really inside the glass. Also, sometimes items appear to be in front of you when they are really above you (on a cliff, ledge, etc.)

undefined When loading a singleplayer map or logging onto a server you are able to move, but after a few seconds movement freezes. You can't move, activate chat or the inventory. You are still able look around and destroy blocks. After hitting a block it appears that you once again are able to move around, activate the chat and inventory. This is a Bug and an Annoyance that has been around since update 1.8 beta or around there.

Annoyances a! Random floating tripwire: When i want to quickly make a path of tripwire i hold the right mouse button in and move along the path. The problem with this is that when i right click on a piece of tripwire, another is placed above it, which is a bit annoying. I think a good solution to this would be to make it so tripwire cant be placed in the air unless another tripwire is next to it.

a! Villager trading is made cumbersome due to the nature of the offer renewal feature. On average, an offer can be used 7 times before a player must trade with the final offer slot to renew disabled offers. Because rarer offers are weighted to be more likely when a villager has many offers, and rarer offers tend to be more expensive or provide items which aren't as useful in large quantities, a villager which has been traded many times tends to be less useful than a villager traded only a few times. This is because, in order to renew desired offers, often an expensive or limited-use offer such as 11 emeralds for a watch must be traded. Once a villager has all its offer slots, further trading with this villager will require trading always with the last slot, putting a player at an excess of an item they may not have a use for. There is no particularly logical reason a villager can't renew their offers after making any other trade: in fact, if we assume villagers have actual jobs aside from trading, offers should be capable of renewal over time. It would be much less cumbersome to trade with villagers if *any* trade had a random chance of renewing a disabled slot. Also, it is not logical that only disabled slots can be renewed - why is there a limit to how many uses any offer can gain? Surely, if a villager amasses larger amounts of wealth, they would have more to trade and therefore be willing to trade more. Jeb has stated he intends for villagers to have more long-term benefits, but currently you are still better off building villager breeders than spending your time caring for any one particular villager. --WolfieMario 01:25, 15 August 2012 (UTC)
 * Very nice analysis. They keep saying they're trying to dissuade us from killing villagers, but the problem isn't that we kill them, it's that we MUST kill them in order to have anything even resembling a useful trading system. --5thHorseman 22:22, 16 August 2012 (UTC)

a There is no way to teleport a player relative to their current coordinates using command blocks. Although the idea may seem simple, there are many things which are not possible because of this (e.g. illusions to help stitch together separate areas of maps, forcefields which physically repel the player (rather than placing them at a fixed coordinate), interactive "flipbooks", etc.). There is also no way to teleport a player to fractional coordinates (e.g. y=64.5). --WolfieMario 01:26, 3 October 2012 (UTC)

undefined If you bump the mouse in just the right way while placing a bed, you can get a heart-shaped one. I'd be equally happy if this bug was fixed or made into an intentional feature.

undefined If you press and hold left mouse button and move away mouse cursor from the block and/or walk away without letting go of the left button block, at which you had pointed initially, will break after time needed to break it normally. This even can be used to mine several blocks at one time — MiiNiPaaT 14:54, 4 October 2012 (UTC)

a Mushroom blocks cannot be harvested or placed properly. In either case (even when using silk touch or commands), the block reverts to pores on all sides, and the Creative Mode pickblock button simply gives mushrooms. Thus, map editors or tedious piston usage is necessary to build with non-pore mushroom blocks. It does not make sense for Silk Touch to fail to properly harvest mushroom blocks, and it makes even less sense that even commands to obtain special mushroom blocks have them reverted upon placement. --WolfieMario 01:26, 3 October 2012 (UTC)

! Efficiency does not work. (At least at least in multiplayer, I haven't yet tested in single player.)Pokechu22 23:07, 4 October 2012 (UTC)

x Mushrooms of either type can not be planted outside, except under trees, even at night. Otherwise, right-clicking does nothing. This makes growing Huge Mushrooms for harvest rather difficult. You'd have to dig a cave big enough for one, or else find an overhang with enough room to grow one. --Logician
 * Just a guess, but I'm thinking that this might have something to do with the fact that the "sl:" number (I'm assuming it means "sky light"?) in the debug screen remains at 15, even after night has fallen. --Logician
 * With less than a dozen blocks you can make a little shelter, place a mushroom inside, quickly break out one side and the roof and apply bonemeal before the mushroom has time to pop. Given this simple workaround, I cannot see how to justify calling this a major bug. Placing mushrooms outdoors now takes a few seconds rather than less than one second. OTOH I do agree that you ought to be able to plant mushrooms outdoors at night, theoretically. --82.69.54.207

Annoyances 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. However, if the frame is off-map, then it is denoted as a white circle, the same symbol used by players off-map. Perhaps a green circle should be added to reduce confusion? --WolfieMario 21:46, 7 September 2012 (UTC)

a In my opinion, the aesthetics of dyed leather armor are severely crippled by forcing them to contain non-dyed parts. While this may be to reduce confusion in PvP, the same could be achieved just by changing the texture, without forcing dyed leather armor to still prominently display brown. Alternatively, a mechanic could somehow be implemented where both components of leather armor can be dyed, allowing for more aesthetic choice rather than less (one possibility is crafting two leather armor together - another would be to dye leather itself, and craft leather onto armor for colored trim). It doesn't make sense that your character can't dye all of the leather on the armor - it's all the same material, isn't it? --WolfieMario 01:14, 14 September 2012 (UTC)
 * Very strongly agree. As currently implemented this is definitely a backwards step; there's not much point making things dyeable if you can't fully control their colour. The old dyeable leathers looked quite good as actual clothes, the new ones, especially the helmet, make Steve look like a racing driver. I'd be delighted to have both options available; could the old clothes be reinstated, possibly as new crafting recipes for wool or something? --Simons Mith[82.69.54.207] 02:16, 14 September 2012 (UTC)
 * If you make the cloth_1_b.png and cloth_2_b.png transparent, you can dye the complete armor. No problem. ~reptile311
 * This doesn't change its appearance to other players, so it isn't very helpful if you wanted to wear the clothes in multiplayer. --129.49.232.133 17:07, 4 October 2012 (UTC)

a Mobs in minecarts will be ejected upon reloading a world or the chunks they are in. Additionally, in rare circumstances, either the mob or minecart may be displaced, and more often than not this breaks any machine (specifically animal breeding machines) using them.
