Crashing/system

Bugs

[!!] [SMP] Linux Dedicated server went boom after 5 mins of gameplay. I'm really worried about this now. --Shelter 16:56, 19 October 2012 (UTC)

  • Agreed that should be fixed, but you really should use crash with more mem assigned on report (but not too much, iv seen assigning too much memory cause crashes, especially 32bit java). --93.106.181.53 18:38, 19 October 2012 (UTC)
  • Someone else will have to do this as I can't control the memory assigned to me. UPDATE: Your players have to be spread, if you're about 5 people at the same location all the time it probably won't crash as quick.
  • This is looks like memory leak to me confirming this on my server!

Gameplay

Bugs

[!] Invisible spider that is not invisible by means of potion, started killing me after killed by another spider, can't use the world without blowing up the area to kill the spider as I can't see it. Very annoying without cheats if you want to rebuild your area again after blowing it up, plus, it's spider you can't see that wants to kill you.
Happened to me too, but with a skeleton. Upgraded to major bug... this isn't an annoyance. It's broken. Some information: It was a single skeleton across a pit of lava, it killed me, then when I went back it was still there but invisible. I could see exactly where the arrows were coming from but I couldn't hit him as much as I tried, it killed me again. (Jigarbov 02:31, 20 October 2012 (UTC))

[X] Player skins will revert to the default skin. Happens most frequently in this snapshot.--HawkBird 11:07, 20 October 2012 (UTC)

  • This may be not because of the snapshot, but because of the skins.minecraft.net being down. Keep track of the indicator on /r/minecraft, I saw it down earlier today--Svajoklis 13:57, 20 October 2012 (UTC)

[X] When Repairing items, it costs less exp and materials to make the item a 2nd time and put in the repair box than to use the materials to repair EX. My gold sword broke, I could choose to use 4 gold bars and 19 exp to repair, or make a new sword for 2 bars and 15 exp. Whats would you choose? Also its more of an exploit and not a bug.--Avery4life 4:40 pm, 19 October 2012

[X] While wearing diamond armor, anvils only do one heart of damage from falling at any height.

  • Intended and not a bug. That's the Safety Helmet Feature (TM) Dinnerbone, see Issues/Weekly_12w41b. Every helmet - even the leather cap - will protect you from too much damage. --Kumasasa 20:32, 19 October 2012 (UTC)

[X] Nether portals fail to transport certain entities which work fine through End portals. Minecarts, Storage Minecarts, and Lit TNT(pushed into the portal via piston) all tested and failed to go through, Arrows were iffy as well. - Malsententia 16:27, 19 October 2012 (UTC)

  • Well, nether portal is not instant. But that will cover only arrows. --93.106.181.53 16:52, 19 October 2012 (UTC)
  • Nether portals are instant for everything but players. All other entities that do work, do so almost instantaneously. Malsententia 14:21, 20 October 2012 (UTC)

[X] Minecarts with mobs/players inside can't go through any kind of portals. --X 11:57, 20 october 2012 (UTC)

[!] [SP] Windows Every 5 - 10 min the minecraft client freezes for 2, 3 seconds and then works again correctly. This is more then annoying when you fight a mob, after the freeze you are mostly dead :). I have only tested it in SP. My Specs are Win 7 64, Java 7u9 64, i7 2GHz, 8GB Ram, Nvidia GT540M 2GB. Normal world, with cheats and chest on. Fps on balanced 60-80. Java is normal started, so I think mc have enough (1024) memory. Today I installed mineraft new, but it further happens. It happens in survival and in creative (adventure not tested). This happens the last two or three snapshots. Have someone the same experience? ~reptile311 Edit: Here is a screenshot [1] from the freeze and a debug-file from the start of the game to the first freeze:

I experienced an issue similar to the one you mentioned after one of the snapshots a few weeks ago. In my case, however, the game quit on its own after about a minute. I fixed it by backing up my worlds and deleting the entire minecraft folder. Then I did a force update, and everything was back to normal. I am able to use all the snapshots and everything too. 173.49.209.151 20:05, 19 October 2012 (UTC)
  • As I mentioned, I fresh installed minecraft and the matter is still present. ~reptile311
Have you tried creating a new world and seeing if the same thing occurs - you world may be the problem, errors do creep into worlds, especially if you have been using it for a while and keeping up with the snapshots
  • I tried it with an old world (12w42b old  :)) and I created a new one (1.4 pre). I notice this the last few (5-6) snapshots, always created a new world. ~reptile311

[X] When setting the gamerule mobGriefing to false, Creeper explosions will still destroy Item-Frames. -- ZerataX 00:50, 19 October 2012 (GMT)

[A] When riding a pig on half-blocks or stairs, pig constantly jumping and ride is very slow. Upside down slabs/stairs works fine. Video demonstration: http://www.youtube.com/watch?v=xHza0CJlaxU&feature=youtu.be -- Cabbagehead9 16:43, 20 October 2012 (UTC)

Annoyances

[A] Naming items shouldn't have an influence on the repair cost of the item, and neither should enchanments determine the cost of naming an item. -- Mustek 14:00, 19 October 2012 (UTC)

[A] [MP] Pig riding seems inconsistent in multiplayer. The pig will sometimes seem to take two bites of the carrot in quick succession (may just be a graphical glitch), and the duration of a boost from a right-click seems to be significantly shorter than in singleplayer (possibly to do with the latency?). Anyone else noticed any of these differences? -TheWyo 03:27, 20 October 2012 (UTC)

Forgot to add, the max speed also appears to be slightly slower, both during normal riding and during a boost. -TheWyo 03:30, 20 October 2012 (UTC)

[A] [Cr] Flowing water can still drag players while flying. --5ives 23:19, 19 October 2012 (UTC)

Hardly see yielding a fully grown wheat drop 3 seeds, mostly they drop one or even no seeds(Tested with 55 wheats, they dropped 70 seeds in total). Not sure if it's because the code has something wrong or I have a bad luck. 115.193.131.100 11:09, 20 October 2012 (UTC)

Fixed/skipped

Blocks

Bugs

[!] There is a collision bug with beacons. Frequently, you would collide with the blue thing. And sometimes the whole block becomes non-solid. This is extremely annoying as you may fall through the block when walking on it. It has been happening since beacons got that texture. But it seems to happen more frequently in this snapshot. --HawkBird 11:04, 20 October 2012 (UTC)

[!] Repeaters that are powered by another repeater, but do not point at a repeater themselves, will not turn off.

  • I assume this has something to do with the ticking system. I'm not sure how fast that pulser is, but I do know that repeaters stay on for one tick. This goes for turning off too. If it sends off for one tick every two ticks (which is what I'm assuming), then each repeater will stay on for, um, one tick every two ticks. I'm not that good with redstone circuits myself, so I have a feeling this comment isn't very helpful. --Mario-Fan 06:22, 20 October 2012 (UTC)

[!] When powered from a button repeaters will not turn on for more then a moment even when they become locked while they are on.

[X] Breaking a block next to, above or below an open trapdoor closes it. --5ives 11:25, 20 October 2012 (UTC)

Annoyances

[A] While standing on a ladder (using shift) and trying to destroy another ladder block it's bounding black box just flickers and the stone behind it gets all the "damage"--Svajoklis 18:30, 19 October 2012 (UTC)

[A] Carrots should require water to not pop out, and they do. Potatoes and wheat shouldn't. Also I have talked to real potato farmers and they say that potatoes require dry ground (not absolutely dry, but dry). So maybe they should require be dry or poisoned potatoes are more frequent. --93.106.188.202 20:04, 19 October 2012 (UTC)

[A] Anvils break far too easily. I have a zombie dungeon XP farm and was going to rename all my diamond tools before enchanting them, and the anvil broke after renaming only about 32 items. It doesn't seem right that a crafting table is made from wood and never breaks from crafting, while anvils are made from iron and break easily. I can understand anvils taking damage from falling, but not from renaming/repairing.--JNRM3 22:00, 19 October 2012 (UTC)

Fixed/skipped

[X] Was busy in my branchmine, when suddenly I broke a block and this silverfish came. I searched everywhere for a stronghold. None found, I even used cheats. Was on y = 10 by the way. [2]

  • Since one of the snapshots silverfish blocks can spawn anywhere underground but in really low rates
  • Neiter bug nor annoyment, since 12w38a they will spawn outside from fortresses. see Silverfish --Kumasasa 18:39, 19 October 2012 (UTC)
  • Moved to the Fixed/skipped section. --GALAKTOSTalk – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 12:37, 20 October 2012 (UTC)

Items

Bugs

[X] When you drink a Invisibility potion, then in Third-Preson mode the held item does not swing properly.

[X] Markers on the map don't disappear after removing the map out of frame... Community map can be flooded by green markers...

Annoyances

[A!] [Su] Expensiveness still counts to say too expensive when NAMING items. (even sharp 5,kno 2,fire 2,loot 3 should be nameable.)--93.106.181.53 18:08, 19 October 2012 (UTC)

World generator

Bugs

Annoyances

Fixed/skipped

Mobs/NPCs/animals

Bugs

[X] Zombie Pigmen spawned by portals in the overworld within the portal block are immediately transported through the portal that spawned them, rather than being treated like an entity that just came in through the portal. As a dramatic example, idling near this for an hour or two, will result in something like this when you go into the nether. - Malsententia 16:28, 19 October 2012 (UTC)

[X] Zombie pigmen do 6.5 damage on Hard, 4.5 on Normal and 2.5 on Easy instead of the intented 3.5, 2.5 and 1.5 because of the added sword damage. Most likely not intended because this makes fighting pigmen too hard compared to previous. --212.226.57.141 14:51, 19 October 2012 (UTC)

[X] The Enderdragon will break blocks even if gamerule mobGriefing is set to false. --84.57.88.93 16:10, 19 October 2012 (UTC)

[X] Slimes will trample farmland even if gamerule mobGriefing is set to false. --217.247.197.215 19:39, 19 October 2012 (UTC)

[X] Stairs in the towers of the desert temples are oriented incorrectly due to the world generator making another stair instead of a solid block of sandstone that causes the orientation to go all weird. --Kytech 23:02, 19 October 2012 (UTC)

[X] Mobs that have traveled by minecart will appear to teleport back to where they entered the minecart and glitch into the ground when their minecart is broken. While the mobs appear visibly to be in their original location, they are physically where they are supposed to be. 00:30, 20 2012 (UTC)

[!] Trading wheat with villager does not work correctly in old or new village. Trading worked partially with wool, then stopped working after a few stacks were exchanged for emeralds.--68.55.140.185 04:48, 20 October 2012 (UTC)

[X] When in a world from a previous version, right clicking any pets will cause all mobs within the loaded chunks to fall through the floor and suffocate. This is very annoying and problematic.

Graphical/lighting

Bugs

[X] The player's legs do not line up properly with the torso. It seems that each leg is set back a few pixels, and each leg is set inward a few pixels (legs overlap one another on their inner face). -- Gilmoreja 15:31, 19 October 2012 (UTC)

[X] Upside down halfslabs are lit wrong. --Melon 18:41, 19 October 2012 (UTC)

  • They removed the new lighting engine and pushed it to 1.5 because it caused to many problems. --☺ Sven ? ! 20:32, 19 October 2012 (UTC)
File:Cracksbug.png

Cracks "block" from 12w42 a but same behavior is present in 1.4.

[X] If a Zombie is stopped before it finishes breaking a door the cracks it made are left behind, then if the door is removed it leaves behind a "cracks block?" (not an actual block). If anything is put in it's place even if it's a different shape (e.g. Fence) the cracks wrap around the object though it doesn't become damaged. The "block" and it's affects disappear after a few seconds or a chunk reload. --5ives 22:04, 19 October 2012 (UTC)

  • Noted in Release 1.3.2 as well, really old bug. -- Featherwinglove 13:17, 20 October 2012 (UTC)

[X] Instance of front lower stair rise in cobble stair not rendering just after being placed. The stair was placed on top of a grass block that was generated in 12w27a, and was placed behind/above a cobble stair block that was placed in 12w27a (this is the New Players' Guide world, I'm doing work in the spawn area.) Interesting thing is that the front face of the second rise is rendered underneath the first run; it is never normally possible to see this surface (nor is it ever built in real stairs.) Could it be that the first rise is set back underneath the second rise? Backing out and reloading the world resumes normal behaviour. In a different world, same seed (no noticed generation differences) generated and played in 12w42b for testing yesterday, the stairs were behaving properly. -- Featherwinglove 13:17, 20 October 2012 (UTC)

[X] In every snapshot after the last full release of 1.3.2 that I have checked and now the 1.4 Pre-release, the clouds block sight of any blocks above them. This only happens when below the clouds. If you are above the lower cloud edge, you can see all blocks above it and looking down, you can see all blocks below. Example This has been checked on Win 7 x64 with an AMD Radeon HD 6870 on several drivers including the latest beta driver. In every test, this did not affect 1.3.2, only the snapshots and the Pre-Release after. --Sysfailure 15:31, 20 October 2012 (UTC)

Annoyances

[A] When reaching the end of a nether portal, the animation plays (even in creative) forever and never sends you back until you step out of the portal. --5ives 22:04, 19 October 2012 (UTC)

  • I think this is intended behaviour, I've never known nether portals to behave any differently. -- Featherwinglove 13:17, 20 October 2012 (UTC)

Fixed/skipped

Sounds

Bugs

[!] Minecart sound does not normally play. If you pause the game with ESC and unpause while riding a minecart, the sound will begin to play, but will not stop again until you are out of the minecart and pause/unpause the game again. It seems that pausing and unpausing the game causes the sound engine to update whether or not the minecart sound should be playing. Running on Java 7 64-bit, Windows 7, quad 2.66GHz, 8GB RAM, NVIDIA GeForce GTS 450 Nitwon 20:58, 19 October 2012 (UTC)

Got the same problem except they start when the minecart starts. Do not end until you pause/unpause or re-log though.

[!] This was in the last snapshot and I have confirmed it still exists in the pre-release. Screenshots are from the last snapshot but are still valid examples. Sometimes the sound engine gets caught up with multiple overlapping sounds and vastly increases the CPU cycles it uses and causes lag because of it. Example Normal use is under 1% but it can easily rise to 20% to 30% and over 60% in extreme cases Extreme example. --Sysfailure 15:27, 20 October 2012 (UTC)

Annoyances

[A] Anvils make no sound when they break. -- Mustek 13:35, 19 October 2012 (UTC)

It's only your problem, i can hear the sound. --Raffox97 13:41, 19 October 2012 (UTC)
  • Try breaking them by dropping a damaged anvil from a high altitude, they just disappear without making sound. -- Mustek 15:05, 19 October 2012 (UTC)
  • Have you download the new sounds? ~reptile311

[A] Holy moly, the new bat sounds hurt my ears. It's too high pitched -- MrScaryMuffin 22:35, 19 October 2012 (UTC)

[A] Throwing an Eye of Ender or Ender Pearl underwater plays the splash sound repeatedly until it reaches the surface or gets picked up. --5ives 22:42, 19 October 2012 (UTC)

Menus

Bugs

[X] When turning fullscreen off or on in the video settings then hitting F11 to switch back it doesn't work and the fullscreen status is incorrect (assuming was correct in the first place) e.g. it says 'Fullscreen: ON' when in windowed mode. --5ives 22:44, 19 October 2012 (UTC)

[X] When saving a screenshot then clicking on the file name in the console, Minecraft treats it as a link to a website and opens for e.g. '2012-12-25_00.00.00.png' in your default web browser without a 'file:///' prefix. --5ives 22:44, 19 October 2012 (UTC)

[X] There's a bug where if you refresh your multiplayer server list, where it SHOULD say: Polling... ; this MIGHT happen (proven by screenshot): Screenshot. jozzamay. 14:13, 20 October 2012 (CET)

In-game interfaces/HUD

Bugs

[X] Text boxes reset when the window changes size or fullscreen/windowed mode is toggled. --5ives 23:10, 19 October 2012 (UTC)

[X] If the inventory is open when a potion affect is cast upon a player the status doesn't show unless a potion was affecting them before it was opened or until it is re-opened. If the inventory is left open as an affect wears off (assuming the status is there) it remains pushed over as if the status was still there until it is re-opened. --5ives 23:10, 19 October 2012 (UTC)

[X] None of the F-buttons (including F3's combinations) work while the inventory (or other interfaces an anvil) are opened or the game is paused except for: F2, F11 and I think F3+S (worked in 1.2.5 and 1.3.2). I couldn't figure out a way to test F3+T and F3+S (only when my sound isn't working), can anyone help me out? --5ives 23:10, 19 October 2012 (UTC)

[X] When your "pick block" control is set to either the left or right mouse button, that button (in GUIs) will behave like the middle mouse button/shift-click.

Annoyances

[A] The text on the anvil (while using unicode font) is in a completely dark gray background (that is not wide enough for text). I believe the solution would be to reduce the "offset" for shadows to one pixel (because the english font is two pixels wide and the unicode one is one pixel wide on the normal GUI scaling). Examples: here--Svajoklis 14:41, 19 October 2012 (UTC)

[A] The performance graph covers the pause menu. Should this be labeled a bug? --5ives 23:10, 19 October 2012 (UTC)

[A] The game cannot be auto paused when the inventory (or other interfaces like an anvil) are open. Some people trust the game to pause when the window's focus is lost. --5ives 23:10, 19 October 2012 (UTC)

Fixed/skipped

Chat/commands

Bugs

[X] [MP] Teleporting to another player via the /tp command does not work cross-world. The teleported player will end up at the coordinates of the target but stay in the same world. --84.57.88.93 16:09, 19 October 2012 (UTC)

  • It's been like that since ever.. --94.230.84.96 20:42, 19 October 2012 (UTC)

[A] In Pirate Speak Cobblestone and Gravel are both called "Pebbles". Given their similar textures, this could cause confusion. --5ives 23:13, 19 October 2012 (UTC)
