Crashing/System
Bugs

!!For the last four dev builds (ever since 12w16a) after about 5 minutes of being connected, the server disconnects the client and creates a crash report. After this, the server becomes unresponsive over the network, but still responds to console commands. undefined


 * I also consistently get a disconnection after about five minutes, but on my iMac (2.5GB 2.16GHz Intel Core 2 Duo running OS 10.5.8) it's harmless. I can just reconnect and continue. 82.69.54.207 18:35, 10 May 2012 (UTC) My "Relevant Details" (cut and pasted from a different crash) are:

!! When you die from a dispenser then the game crashes. Dinnerbone had fixed this in Bukkit by making it say "shot by Herobrine", but no fix has been added to vanilla. TorchicBlaziken 01:12, 15 May 2012 (UTC)

!sp When attempting to enter a world it displays the following text: "Failed to connect to the server Connection refused:connect" ~Flyingwalrus33
 * Usually that issue is accompanied by an error report logged in your .minecraft/server folder either in a server.log file or in its own file. Could you check for it and post it here? Mojang said they had fixed this issue so its probably quite important. --Mattrition 08:33, 11 May 2012 (UTC)
 * They need to change server so players can join before it has loaded/generated level. I think what happens is it tries to connect before loading/generating is done. --188.238.193.231 10:02, 12 May 2012 (UTC)

here is my report undefined

!sp There is an allocation bug between the client and the new "Listen" server. Allocation of Ram can be applied to the client without any problems.. The real problem is that the allocation is not bound to the "Listen" server. Whenever you enter the new Singleplayer and the "Listen" server is started up, (If it was run from command line) it will display the error message of "[Warning] To start the server with more ram, launch it as Java -Xmx1024M -Xms1024M -jar minecraft_server.jar"  Then the following messages might be displayed. "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" Therefore, users may experience unnecessary server sided lag which can be prevented. A simple fix, if possible, would just be to bind the allocated ram to the "Listen" server as well. Dedicated servers work as normal with/without allocation. --JDos17

undefined Because of the new SP-Engine, it's not possible to convert a world from MCRegion to Anvil, I got this when I tried to convert (it's not a crash) undefined. Before test it with a error bat, I got a crash... --Galaxy_2Alex (Talk)
 * The above error most definitely does not have anything to do with world conversion. It rather means that there still is a server running (or you have another program listening on that port). Gitterrost4 19:33, 19 May 2012 (UTC)

undefinedsp Because of the new SP-Engine, it's possible to save different locations for each account in SSP map. Connecting secondary account whilst the primary account is already connected to SSP map causes secondary account to gain primary accounts location and inventory, and after a while the primary account will be disconnected.

Gameplay
Bugs

!! If you shot an Ender Crystal it sometimes freezes the game and then throws a readTimeout error. Some Crystals can be shot and explode normally, others will always lead to a freeze. When you close and re-enter the game again lots of enderdragons appear. As stated below, this happens when two ender crystals are so close they trigger a chain reaction when one of them is destroyed. In these cases the end becomes unplayable.
 * Interesting. Someone paste a crash report! --Mattrition 08:48, 17 May 2012 (UTC)


 * First crash

undefined


 * Second crash, already multiple dragons, same crystal shot

undefined


 * I did some specific testing and narrowed it down. The server crashes when two (or probably more) crystals are so close together that they create a chain reaction. Shooting one triggers the visual explosion of the other and crashes the server. Then all mobs on the client freeze until the timeout makes the client quit. (bytemage)

undefined You can only shift click bottles into the first two slots in a brewing stand. You should be able to recreate it simply by trying to shift click three bottles into a brewing stand --74.76.230.208 22:20, 22 May 2012 (UTC)

undefined sp Time occasionally slows, including mobs, etc. When it does, it takes around 5 seconds for a mob to take damage when hurt. It takes 5 seconds for the player to take damage when hurt. Also, there are 2 bars out of 5 when viewing the list of players in singleplayer. (Radionactive 00:55, 16 May 2012 (UTC))
 * You are literally just describing lag. --Mattrition 09:28, 16 May 2012 (UTC)
 * I see. When I start the game via a command-line, I see a new "Can't keep up!" message every 3 or so seconds. No errors, or anything. I always have this issue when I host a multiplayer server, and I was surprised to see it on singleplayer. I've tried dedicating more and less RAM to the game, but 2GB or 512MB were as far as I took it, neither having any effect on performance. (Radionactive 19:53, 16 May 2012 (UTC))

undefined When the Bonus Chest is enabled, if Minecraft populates that block space with another block, the chest is destroyed and the items in it become drops. This is especially susceptible to snow cover and jungle undergrowth. I can't give you a seed, because the f3 feature shows seed no longer
 * I'm not able to check if it still works, but the seed "walruswalruswalrus" used to be a good example of a snow biome preventing chest placement. --Mattrition 10:42, 11 May 2012 (UTC)

undefined The "Logoutivator" bug: it is possible to teleport the player from the caves deep below all the way to the surface using a trapdoor. All that is required is to put a trapdoor at the waist level in a room with two high ceiling, open it, step inside, close it and log out while player is "inside" the trapdoor. Logging back in, the player will be teleported to the first empty space above the ceiling, which is usually the surface of the world. This was previously a bug only encountered in SMP, but now it can be reproduced in single player as well. --Kcin 19:59, 11 May 2012 (UTC)

undefined If you play offline and you enter your single player world, your inventory and spawn will be reset. --Kcin 12:11, 13 May 2012 (UTC)
 * It won't be reseted. Since SP is a local server if you are not signed in, Minecraft thinks that you are some random new player because it see you like player not your MC nickname. --Wylify 06:52, 19 May 2012 (UTC)

Annoyances a! The enchanting system has always, and continues to be frustratingly unfair. sometimes producing Efficiency III when a level 50 enchant is used. Considering you need to kill NINE HUNDRED AND TWENTY FIVE zombies/creepers etc., to get to Level 50, users are naturally in consensus that, to quote Yahtzee Croshaw, the ratio of difficulty to find versus actual usefulness is completely arbitrary. While we respect the mystique Mojang have tried to create about enchanting, the numbers need serious review. Kizzycocoa
 * Use a level ~30 enchantment. You'll get stuff like Fire Aspect, although not as high-leveled.
 * The solution is not to go lower for enchantments. if so, there's no point in the higher enchantments. --Kizzycocoa 23:11, 10 May 2012 (UTC)
 * The solution is to make the enchanting system not act like a game of chance. If you have to work for something it should be rewarding, at least in a game.

a Books on enchanting tables no longer seem to open when you walk toward them --74.76.230.208 22:20, 22 May 2012 (UTC)

a The enderdragon attacking as soon as you enter the End is extremely unfair, especially when playing on hardcore and spawning off the main landmass. Before you have time to orient yourself and build a bridge you are very likely pushed of the spawn platform and dead. For a hardcore game there is no more frustrating end than being killed by plain bad luck. The enderdragon should turn hostile only as soon as you hit him or any of the endercrystals and maybe any of the Endermen. That way you'ld have a chance for a fair fight even when spawning in a bad location.

a Apart from the enchanting systems randomness, making xp needed for levels increase linear would remove the need to grind to the exact level you want to enchant something with, and make enchanting something you can do after exploring/fighting for some time and then spend the levels on more than one enchant. At the moment not spending the full amount of xp you accumulated is just stupid, making the random levels of the three available enchants just annoying as you have to "reload" until you get one at the max possible level. But this is really just secondary to the frustration of the randomness of enchants.

a Pick block doesn't select water buckets when the player picks water. Also for lava. Instead, it picks the block the player is looking at though the water, if it is close enough to be picked.

a Flaming arrows do not create fires on wood, activate TNT, or burn the player when the rested arrow is stepped on.

a Players can never see their score unless they die.

a As has been witnessed in older versions, if you increase your flying altitude until you come into contact with a ceiling, you can move freely about the space. If, however, you fly to an area with a higher/no ceiling (whilst maintaining the same altitude), you cannot fly back into that lower area without lowering your altitude (as it believes that the player is coming into contact with the side of the block above). This is particularly frustrating when exploring caves or building underground.

a Iron armor is way overpowered and imbalanced: without armor you're useless, with you're immortal against mobs. It takes away a lot of challenge from the game. Diamond armor is even more overpowered, but it lasts too short to be useful.

undefined If you sleep in a bed with an inverted staircase above, when you wake up you can clip (harmlessly) into the staircase block. (I was using stone brick stairs and a ceiling height of 2 at the edge of the room, 3+ in the middle. Bed at edge of room.) 82.69.54.207 23:45, 10 May 2012 (UTC)

undefined (SSP) Sometimes, when pistons move too fast like in a BUD switch, the block seems to be on the retracted piston but serverside is pushed away. When relogging you can see the real block. This can get you stuck until relogging if you walk over the invisible block.

undefined ? Normally, when you place a block, you place a block. I've just started noticing that if you place a block close in front of you (possibly inside one block's range), you place it and pick it up again in the same instant. I've seen this for sure with stone, glass panes, fences, and a bucket of water. When I did it with the bucket, the bucket graphic changed to empty, and the water disappeared without trace - no flowing water in the world at all, although it still repelled a hostile Enderman. But right-clicking retrieved the water from whatever limbo it was in, possibly only because I hadn't moved in the meantime. The water symptoms seemed a bit like server lag, but I'm playing single player, and no matter how long you wait the water never shows, even though you can retrieve it by right-clicking in/on the right place. 82.69.54.207 13:17, 13 May 2012 (UTC)
 * Since 12w18a Singleplayer IS Multiplayer...  05:04, 17 May 2012 (UTC)
 * I know that. The point I was trying to get across was that this is the only occasion - and it is pretty specific - under which I've ever seen laglike symptoms. So it's unusual enough to be worth mentioning. --82.69.54.207 11:47, 17 May 2012 (UTC)

undefined If you put a block on a grass block in a jungle biome near the coast, the grass turns into sand when you remove the block placed on it.
 * This is likely the World Generator bug mentioned below (about trees and generated structures); beaches are actually special biomes that overwrite existing terrain, and a world generation bug causes terrain to appear as it was originally until blocks are updated or you disconnect/reconnect.184.166.122.245 18:53, 19 May 2012 (UTC)

undefined Blocks placed in empty chunks in the end are invisible until reconnecting.

undefined Cocoa beans will not always be destroyed by pistons that "slide" past the cocoa plant. To reproduce create a wall of jungle logs and have pistons push the wall upwards or downwards with cocoa plants attached. Some of the plants will pop off some will stay when the pistons are activated. The plants that are on chunk boarders tend to stay.

a It is too hard to open Iron Doors. Using a button only opens them for a small period of time in which many players do not have time to get through the door. Using a lever doesn't help because you can't close the door on the other side. Using a pressure plate is the fastest and easiest way to open an Iron Door, but non-player mobs can activate it.

a Moss stone retains the Cobblestone texture pattern from before 1.7, clashing them slightly when placed together.

a! The golem recipes do not care whether the blocks are freestanding or part of a larger structure, so structures made of iron or snow blocks can be griefed by Endermen placing down pumpkins. TorchicBlaziken 01:11, 22 May 2012 (UTC)

If you created several at once, they'd all be centred on the same spot, so in single-player the duplicates aren't much use. But place crafting tables in a series of new locations, create maps there, and you should get map_1, map_2 and so on. [Late Edit: Also, if you shift-click when completing crafting the map, apparently that always gives clones of map_0 too. That's a known quirk of the system, (which I'd class as a bug, personally) but you don't mention shift-clicking in your report.] 82.69.54.207 12:47, 14 May 2012 (UTC)

undefined Water sometimes will not appear when poured from a bucket in survival. I also see this with lava. The lava usually does appear in the world for a brief instant before vanishing, whereas water only appears sometimes. Clicking again on the same spot without moving retrieves water even if invisible, but not lava. This seem to occur most reproducibly deep underground. On the surface, water can be placed just fine. Finally, sometimes when water is placed underground it does appear, but it just sits there and doesn't flow, or the flow doesn't shut off when you retrieve the source block. y=12-13 appears to be the key level to look at. It's like there are two types of water and lava. Collect the from level 12-13 or below and you have phantom water/lava that disappears (permanently) as soon as you try to place it, use it, move it about your inventory etc. 'Real' water and lava still behave oddly if placed at or below level 12-13, but they will behave more-or-less normally if placed above that level. --82.69.54.207 16:28, 18 May 2012 (UTC)

a When destroying a block with 0.0F of hardness, it still deducts durability from your sword or tool. These are blocks such as torches, tall grass, flowers, saplings, mushrooms, and crops. This makes it so that you always have to switch to something else before breaking these blocks or else your tool or sword will suffer needless damage. Usually, this is just a minor nuisance, but it gets extremely annoying when there is a chicken in tall grass and you want to kill it. You can't just use your bare hands because then you wouldn't kill it in one hit, and the chicken would run away. Also, the chicken is one block tall so you often accidentally use it on tall grass, wasting your sword. It doesn't cost durability to put out a fire, so why should it cost durability to break something that you could destroy instantly with your bare hands?TorchicBlaziken 20:47, 10 May 2012 (UTC)

undefined The Ender Dragon will deal collision damage to Endermen in the End. When this happens, the Endermen will become angry at the Ender Dragon and chase her around but be unable to hurt her.

undefined Entity collision does not take into account the dimensions of the entity who is riding it, meaning that spider jockeys and players in minecarts can fit into one-block-high spaces but suffocate. TorchicBlaziken 21:25, 12 May 2012 (UTC)

a The missing collision between players is rendering my one-person-at-a-time entrances to stadiums and some other stuff completely useless. - Floedekage
 * Not to mention it completely ruins some PvP games, like "King of the Ladder". Quite annoying. --Kcin 20:41, 11 May 2012 (UTC)

a Mobs and other living entities do not suffocate in lava because the oxygen meter doesn't take effect. This can be noticed when under the effects of a Potion of Fire Resistance, or on Nether mobs. TorchicBlaziken 20:47, 10 May 2012 (UTC)
 * That has always been the case, (temporary) downgrading to annoyance. 178.84.63.89 18:03, 13 May 2012 (UTC)
 * I don't think that always being the case makes it not a bug, it just makes it an oversight that has been in the game for a very long time. TorchicBlaziken 21:27, 13 May 2012 (UTC)

a Endermen are occasionally exceptionally hard to kill because they teleport a lot, their health is high, and you may or may not even get an Ender Pearl.
 * Actually it's other way around. Endermen are too easy to kill. All you have to do is attacking their feet. Btw: Endermen are meant to be hard to kill.

a There are very few mobs spawning. I built a mob trap underground, filled all caves underground with torches (checked with 3rd party program that I didn't forget about any cave) and there were no mobs spawning. Yes, there spawned two spiders. Once. While the trap was running three days. I was far from the trap so I didn't block spawning. So were all spawnpoints. Why are there so few mobs? I think this is very annoying. I don't even find any mobs on the surface.

a Skeleton are much stronger than any other mobs. They can shoot very quickly, they don't have to draw their bows and they don't even have to face you to shoot!

Fixed/Skipped

Graphical/Lighting
Bugs ! "Phantom" skylight occurs in places where there should be complete darkness. This breaks many maps that many people consider fun and it looks awkward when a zombie starts to combust in a cave. This bug has existed ever since anvil was created. You should be able to reproduce it by building a light blocking structure high over the ground.
 * I should point out that there's actually a mod that fixes this bug, so at least we know it's possible to fix. TorchicBlaziken 20:31, 11 May 2012 (UTC

a Stairs placed in f: 1-3 direction have textures misaligned by half of a block. Stairs placed in f: 0-2 direction have properly aligned textures. This is easily noticeable by examining the stone brick stairs, due to their regular texture, but it is the case with all stairs, just not very noticeable on wooden and cobblestone stairs. It is an old bug. --Kcin 20:09, 11 May 2012 (UTC)
 * Not a bug. The stair textures act like the textures on a block. Imagine doing this with actual Stone Bricks. It would look weird if ALL the blocks actually faced the direction you placed them from. They would look tiled and ugly. Looks like an Annoyance to me. Downgrading.  08:05, 13 May 2012 (UTC)

a The fishing rod is flipped by the coding when held. It should be rotated in the items.png as it looks weird that way. <MCKMan> 19:25, 10 May 2012 (UTC)

a Shears should probably be horizontally flipped in hand (so you're not cutting/shearing things with the blunt edge). --Calinou
 * Use an image editor to flip the shears in items.png. It's not that hard you know? <MCKMan> 10:07, 11 May 2012 (UTC)
 * Not everyone wants to use an image editor you know. 10.120.3.108 14:38, 11 May 2012 (UTC)

 * I think this is a misunderstanding. The white end of the shear is not the blunt end (handle), it is the sharp edge. The two white thingies are the two iron bars sharpened, and they have a wooden handle. The shear design is based on sheep shears, not on common scissors.

asp The seed is no longer shown in singleplayer. - Mustek 14:16, 10 May 2012 (UTC)
 * This is due to that fact that (technically) there is no Single Player in this snapshot. SP is now a locally hosted server, just like if you ran a server and connected to it on the same computer.
 * A good idea is that the op of the server could see the seed. --Snybi 15:26, 18 May 2012 (UTC)
