Crashing/System
Bugs !! Publishing a world to LAN results in the game crashing for me. --Nathan2055 18:59, 27 June 2012 (UTC)
 * No Java crash log. The world returned the published message, but Java stopped responding. --Nathan2055 19:02, 27 June 2012 (UTC)
 * Try launching Minecraft from command prompt.  Maybe command prompt shows something. Use   if you have java 1.6. if you have x64 os and 32bit java, then use   instead.  --188.238.133.80 20:21, 27 June 2012 (UTC)
 * Not sure if this is the right place: Minecraft will not load at all under jre7. I get the launcher, log in, then black screen forever. I have to right click the jar then choose to open it with jre6. I'm on Ubuntu 11.04. 208.107.42.228 20:55, 27 June 2012 (UTC)
 * Ran Ubuntu 11.10 x64 live. Installed oracle jre7. Ran minecraft from terminal. Created world. Opened for LAN. Friend with could not join. Host was seen on LAN search. IP join did not help. Independent server however worked perfectly on Ubuntu. --93.106.18.81 23:53, 27 June 2012 (UTC)

!! ? You get a crash when you attempt to travel from the nether to the overworld
 * This clearly doesn't happen all the time for everyone otherwise it would have been reported just after the snapshot was released. Can you provide a crash report (should be something in your .minecraft directory)? What was your world seed? Coordinates of portals? Can you reproduce the crash easily? etc. --Mattrition 08:43, 29 June 2012 (UTC)

! sp In some computers, Minecraft may save your character's position and items, but will NOT save world changes, making hours of work gone to waste. --Manuelschi 00:06, 28 June 2012 (UTC)
 * "In some computers" can I have an example of such a computer? OS & Java version. Have you actually seen this issue happen in 12w26a, too? We save players and worlds at the same time now, they should never desync. Dinnerbone 10:43, 28 June 2012 (UTC)
 * 2GB of RAM, 32 bit, windows xp SP3, java 1.6. The level.dat files to be the one that updates through time but the region files seem untouched. In 12w24a seemed to save just fine (was unplayable in 12w25a) --Manuelschi 16:51, 28 June 2012 (UTC)

undefinedsp7 64bit Minecraft now and then freezes a few seconds and then again runs normal. I don't know if this happens in MP. I couldn't detect a schema. I start minecraft with the normal launcher. Java is 7u5 64bit and my computer has 8GB Ram. This happened in 12w25a too.

undefined CMD-V does not work to paste things into Minecraft. Dinnerbone said he was having trouble with this because he didn't have a Mac. However, Minecraft recognizes the CMD keys as LWIN and RWIN in the controls menu, so enabling the LWIN-V and RWIN-V combinations to paste might do it. CTRL-V does work on a Mac, but it is unintuitive for Mac users. TorchicBlaziken 21:14, 28 June 2012 (UTC)

a! Minecraft doesn't support Windows1250 codes. I'm unable to write some letters.

a! I have some chunk loading problems, as they load "last minute" or never. Had this problem since 12w25a and it continues in 12w26a. Click here for the video on YouTube, PC configuration is in the description - Singleplayer Creative Mode. --Freakedenough 06:13, 29 June 2012 (UTC)

a! From the moment you start playing Minecraft, you memory usage starts going up. The more you move around and load more chunks, the faster it goes up. So you basically have a time limit before the game begins to lag out and crash. It sometimes (not often) goes down a bit, but then starts going right back up, so sooner or later your game will crash. 76.119.224.99 15:07, 27 June 2012 (UTC)

 * How do you give it one GB of RAM? --76.119.224.99 17:55, 27 June 2012 (UTC)

a! Ok, I have a REALLY old and crappy laptop, an acer with 1.7 GHz and 2 GB of ram. Now, I spawned a flatland world, and my fps maxed out at about 96. But, when I came to an NPC village, it got really slow really fast. My lowest fps was 2. It should be noted i was sprinting, but i was also sprinting before and got 96. I tried 4 worlds just to make sure, and the same thing. Also, when I left the villages, my fps went up to its highest.
 * This is probably due to all the entities that exist and wander about in a village, were you on Peaceful by any chance? I think people complain about slimes giving them lag. You could also try just standing still once you reach a village to see if everything levels out, as well at adjusting the rendering distance to see if that makes any significant impact. 78.145.250.250 02:22, 28 June 2012 (UTC)
 * Well, I did stand still, it did even out, but once I started moving again the lag came back. This never happened with villages before... It probably does have something to do with entities, I also lagged with sheep... XD I was also on the fastest settings for minecraft, and I tested it on my brother's computer, which is way faster, and I still lagged more with the village... Have you tested it? It probably has something to do with the new "Performance Improvement". And yes, I was on peaceful, but I don't see what that has to do with it, after all, I don't want slimes lagging me more.... :/ I was also on survival mode.
 * I used to find this sort of thing during Minecraft Beta, although I lagged extensively (almost to an unplayable level) when I tried moving anywhere not just near villages. Optifine sorted it out, but if it still lagged on a faster computer then it sounds like Minecraft is the problem not an overloaded CPU or not enough RAM. Have you tried setting Java SE as a High Priority?
 * Look: I went back to 1.2.5. Same computer. Same world. None of that sort of thing happened. :/

Gameplay
Bugs

! You can make your world unplayable by going to the Nether and using a portal back to the Overworld with an X or Z coordinate of at least 4,000,000. This is because it will take you to an X or Z coordinate of past 32,000,000, which is considered an illegal position by the game, and you will be disconnected. Normally, when you re-log after an illegal position disconnect, the game will move you to a valid position. However, since you warped there from the Nether, it will just put you back where you warped in from the Nether. So, whenever you log on you will be immediately disconnected for your illegal position, and although it doesn't outright crash the game, it renders the world unplayable for that player. If I were the one who had to think of a way to fix this, (besides making places after X/Z 4,000,000 in the Nether an illegal position which would cause complications since you could use /tp to send someone past there) I would make the Nether Portal take you to the End past X/Z 3,750,000 in the Nether. The reason I thought of this number rather than 4,000,000 is because of the bug below. TorchicBlaziken 22:02, 27 June 2012 (UTC)

undefined If you use a Nether Portal in the Nether with an X/Z coordinate between 3,750,000 and 3,999,999, you will fall into the void and die upon warping to the Overworld. This happens because you will be warped to X/Z coordinates between past 30,000,000 and 31,999,992. These coordinates are in the Far Lands, where block physics do not work, so an exit portal will not be created. So, since there is no clipping, you will just fall into the void, unless you are in Creative and start flying before you hit the Void. TorchicBlaziken 22:02, 27 June 2012 (UTC)

undefined While the /tp command cannot be used to teleport someone past X/Z 30,000,000 because of the Far Lands, the server will not disconnect you until you are past X/Z 32,000,000, so you can just walk right past 30,000,000 and enter the Far Lands, falling into the Void if you're not flying. It would make more sense for there to either be an invisible wall like in Xbox 360 Edition, or it would disconnect you past 30,000,000 instead of 32,000,000.

undefinedmp When leaving the game while sitting in a (still-standing) minecart, the player stands on the block below the minecart when reentering the game. After a jump the player sits normally.

amp Moving a portal in the nether one block cause the portal to jump to one of 4 portals in the overworld. Breaking the new portal in the overworld does force it back to the original portal. However, this is only temporary fix. Eventually the portal jumps again. This issue actually started in 12w23.

undefined Normal-sized mushrooms can't be planted outside at night.

TorchicBlaziken 16:31, 21 June 2012 (UTC)
 * If I recall correctly, this was an intentional change for balance purposes. It was too easy to use a red mushroom and bone meal to make an instant shelter. So you're options have changed to keeping mushrooms underground, or planting a mushroom on a Mycelium block (obtainable via Creative and/or using a Silk Touch shovel on a Mycelium block). Techokami 00:25, 22 June 2012 (UTC)
 * Think about that. Is it really easier to kill a skeleton and make bonemeal, then find a red mushroom and grow it then to just mine a few dirt blocks and build a shack? It's an obvious bug, however it is a feature that they are not able to be placed in daylight.
 * Yeah, I cannot imagine that this was done for balance purposes. If you want fast shelter, it's just as quick and easy to punch a hole in the side of a hill. Quick mushroom houses were not winning the game for anybody. --Rifflesby 23:22, 27 June 2012 (UTC)
 * (Merged duplicate) Mushroom growing still has issues. They were supposed to be growing in dark areas, but now the game only decides if it is in touch of skylight and ignores block light completely. And even if it is night you still cannot place mushrooms. 58.153.143.203

undefined When placing Mushroom blocks of a damage value greater than 0, it will revert to 0 upon placing. This used to happen with Monster Eggs, before they were tweaked in 12w17a to prepare them for inclusion in the Creative Mode inventory.

a! If you are in the end and want to build a bridge away from end-island and build a block at the end of each chunk it will be a invisible / non existing block.

a cr While water and lava don't slow you down while flying anymore, cobwebs still do. TorchicBlaziken 23:28, 21 June 2012 (UTC)

a cr There are a few lines of code in the class for the End Portal block (the actual portal itself, not the frame) that prevent the creation of End Portals in the Nether or End except for like a split second after the Ender Dragon dies, even though this doesn't matter because you can't even make them in Survival. This only serves to prevent the player from replacing an End Portal in the End after a player in Creative destroys them. TorchicBlaziken 22:39, 7 June 2012 (UTC)

a Pumpkins still cannot be placed on air blocks, i.e. placing them on the side of blocks when there is air under them. This is just annoying because the player has to place pumpkins on a block, but they can just remove the block after without the pumpkin "popping" into item form.
 * You cannot place lit or unlit pumpkins from below to a block. Same as above. You always have to use a help construction. image:imgur.com/W9OCF --reptile311

a If you place a slab on a grass block (that has tall grass on it) from above (standing next to, looking down at where you are to place the slab), the game erases the grass and sets the block on the top half of the box. Common sense would say that the slab should replace the grass but be placed on the bottom half of the box. I assume this happens because the game uses the grass' bounding box to determine if the slab should be placed in the upper or lower half of the box. 5thHorseman 19:00, 28 June 2012 (UTC)

a! Download my map. my map Directly in front of the player is a cave. Try to go down. BOOM! A whole chunk disappears and seems you can drop down to oblivion. You cannot drop easily though, because the player is stuck in some invisible tile or something (no suffocation). You can go down sometimes with some cursor-key jerking. I have dug around and found that water and lava does not drop in there. Mobs CAN drop in there including myself. Happens with w26, but also w25 and w24 too. Don't know if it goes further back.

undefined Mobs, including the player outside of Creative Mode, can breathe under lava. This is an oversight that has existed ever since Indev when the air meter was added to water, but Notch apparently forgot to add it to lava because back then it was impossible for any mob to survive under lava, which has changed since the addition of naturally fire-immune mobs in the Nether and potions of fire resistance. TorchicBlaziken 23:22, 21 June 2012 (UTC)
 * I don't think that is a real bug, because it does not matter at all. Regular mobs and players will burn to death anyway and nether mobs are not realistic at all, so they don't need to act in a natural way, too. And if you are using potions for becoming fire-resistant.. come on, we are talking about a game. --Murrrmel 10:40, 28 June 2012 (UTC)

 * Please don't try to guess what is my opinion. By the way: breathing underwater may be a suggestion for a new poison. What I was meant to say is: the ability of breathing in lava don't interfere with the usual gameplay. The player and most of the mobs usually will just burn to death, no matter if they can breathe or not. So, in my opinion it is not really a bug. Also, making the game code more complex because of trivial issues costs valuable performance. --Murrrmel 14:58, 28 June 2012 (UTC)
