Crashing/System

Bugs

[!!] Crashing upon creating a new world. World created using seed "kingpunchwood". Game crashed a few seconds after spawning in. --Nathan2055 16:00, 24 July 2012 (UTC)

  • World is stable after re-entering (apart from lag). It apperars to be an issue with terrain-gen. --Nathan2055 16:59, 24 July 2012 (UTC)

[!] Minecraft will STILL not save any world progress on low-end computers (1.75 GB of RAM, 32-bit, 2.71 GHz, Windows XP SP3, Java 1.6) --Manuelschi 16:25, 24 July 2012 (UTC)


Annoyances

[A!] Frame rates dropped again. at w25 was back to 100+fps, now back to around 30 and locked to chunk updates. memory usage I/O rate seems to be crazy high as well --Porrohman 20:11, 24 July 2012 (UTC)

Gameplay

Bugs

[!] Entering a nether portal caused the screen to go black and the player was dying. He exited the game and logged back in and died. Looking at the server log I pulled this:

Notice the Y:-82. The server is running Ubuntu 12.04 (32bit sun java 32bit), 2GB RAM (1.5GB for minecraft), SSD HD.-jc2xs- 50.77.77.102 14:47, 24 July 2012 (UTC)

  • (Merged duplicate) Entering a nether portal will sometimes (about 1/3 of the time) spawn you into the void. --this_thadd 14:39, 24 July 2012 (UTC) (downgraded to annoyance, I'll let the regulars chose the severity, this is the same issue as reported below by gh0straider)
  • Upgrading bug to major and removing multiplayer tag. --Nathan2055 15:22, 24 July 2012 (UTC)
  • (Merged duplicate) When entering the over world from the nether, if you move while the screen is black, you will be stuck, then fall into the void. If you quit then restart, there will be a giant world hole. If you quit then restart again, it will be gone.

[X] Logging out and logging back in while falling off a cliff will only make you take the fall damage from the height you logged back in from. It is extremely annoying with fall traps on PvP servers.

[X] Vines, tall grass, or lily pads held in third-person (F5) appear gray

[X] Boats still exhibit glitchy behaviour when pushed against walls. -- 14:25, 24 July 2012 (UTC)

[X] When in a boat, opening and closing your inventory in survival mode will cause the players arm to be rotated improperly. -- 14:51, 24 July 2012 (UTC)

[X] Firing arrows from a bow in superflat worlds can be glitchy. -- 15:14, 24 July 2012 (UTC)

[X] Zombies inch forward very slowly for 3-4 seconds after being hit with a sword. -- 15:49, 24 July 2012 (UTC)

[X] [MP] When teleporting to the nether the server lags. A noticeable spike on the server client appears also. Screenshot: [[1]] --derksthename

[X] (12w30_B_): Block breaking speed is not properly controlled by the server. http://www.minecraftforum.net/topic/1371155-12w30b-snapshot-ready-for-testing/page__st__160#entry16728430 Specific issue: A line of gravel blocks, two clients, and diamond shovels vs. hands. Both clients are 1.42 GHz PPC's; one has the server, one does not. The one with the server gets a significantly lower frame rate. Breaking by hand, they are almost the same speed. Breaking by diamond shovel, the lower frame rate computer runs much, much slower. --Keybounce 17:52, 24 July 2012 (UTC)

[X] With some bed placements, you fall out of the bed instead of sleeping in the bed. See File:Falloutofbed.png to reproduce this. Seems like some part of the game code still thinks the player is standing, so it's trying to prevent him from suffocating by pushing him away in some direction. -- 79.235.239.111 20:47, 24 July 2012 (UTC)

[X] (12w30_b_) Two clients (an i7, a PPC) connecting to an i7 host; both playing with boats. The 6-10 fps PPC has better control and less jerkey-ness when turning than the 25-33 fps i7. Neither has good control at near-0 boat speed. Both will see the other boat move properly, and will _sometimes_ see the other person move with the boat, and sometimes not see any movement of the other person at all. --Keybounce 21:32, 24 July 2012 (UTC)

[X] Attempted to teleport while in a boat. Expected behavior: Teleport to new location, keeping facing, staying in the boat. Actual result: Out of boat, same location, not teleported, however the message from the server says I am teleported. Oh, and sinking down into the glub water.

--Keybounce 21:32, 24 July 2012 (UTC)

[X] When a boat is placed, it seems to always face west (sunset, f:1). Regardless of your facing when you place it.

[X] Boat race: Three machines, an i7 (host), a PPC/9200 (two machine hop to host), a PPC/9550 (one machine hop to host -- same wifi).

All three machines started at the same speed. At some point, the PPC/9200 dropped behind the others. Speed of all three stayed the same until one boat hit an obstacle and sank.

i7/Macbook pro did NOT stop when the up arrow was released -- two tests, about 40 seconds constant "forward", and on release it kept going (apparently did not see the key-up.)

--Keybounce 21:32, 24 July 2012 (UTC)

Annoyances

[A] Mobs spawn on non-natural occurring blocks Djerun 12:47, 23 July 2012 (UTC)

  • See discussion talk:Known_bugs/Version_12w27a#Mobs spawning on 'non-natural' blocks --80.134.11.177 12:52, 23 July 2012 (UTC)

[A] The player doesn't get moved/pushed by other mobs/entities (including other players), while this happened in 1.2.5 and before. Might have to do with the singleplayer/multiplayer merge. (or is it intended?) --Gmfreaky 15:37, 24 July 2012 (UTC)

  • This is intended behavior, that was changed last week to fix players being pushed around by animals. --Nathan2055 15:49, 24 July 2012 (UTC)
  • How is that fixing? I thought mobs were supposed to push the player, they push other mobs. By the way, this was not fixed last week, it has been this way since the singleplayer/multiplayer merge. --Gmfreaky 17:21, 24 July 2012 (UTC)
  • Because animals used to push players to the back of animal pins a lot, making it difficult to breed them (also, please keep it civil). --Nathan2055 17:38, 24 July 2012 (UTC)
  • I'd call it a feature, it doesn't make sense to be able to walk through animals. Also, if you're not from Mojang, please don't mark bug reports as fixed, like stated in the instructions.--Gmfreaky 18:47, 24 July 2012 (UTC)
  • Fine, downgraded to annoyance. --Nathan2055 20:19, 24 July 2012 (UTC)

[A] Even at full speed, with the accelerate key pressed, you cannot ram an enemy boat. It's bumper boats, not sinky boats. --Keybounce 21:32, 24 July 2012 (UTC)

Fixed/Skipped


Blocks

Bugs

[X] pistons are allmost fixed but these piston elevator's still don't work properly. they push you up 5 block before you get stuck inside an extended piston arm.--League 19:47, 24 July 2012 (UTC)

[X] If you place a slab on top of an ice block, you will still slide when walking on the slab

  • Ice has always been that way, the slide effect extends half a block up, like the extra-tall effect of fences. --Acomputerdog 21:14, 24 July 2012 (UTC)

[X] FallingSand entities spawned from Mob Spawners appear as Gold Ore. They appear as the correct block once settled. (Becoming normal blocks.) --MegaScience 15:00, 24 July 2012 (UTC)

  • Update: It appears this has to do with the Dragon Eggs being Lava bug. FallingSand as TNT appears as Gold Ore. FallingSand as Cake appears as Sand. Should all be patched together with Dragon Eggs being fixed, I assume. --MegaScience 15:46, 24 July 2012 (UTC)
  • (Merged duplicate) Mob Spawners set up spawn non-mob entities such as FallingSand or PrimedTNT will be misaligned and be incorrectly lit. MegaScience 15:00, 24 July 2012 (UTC)
  • Merged duplicate reports. --Nathan2055 15:55, 24 July 2012 (UTC)

[A] Breaking a block underwater doesn't show the breaking animation when standing above water

Fixed/Skipped

Items

Bugs

[X] [Cr] Duplicating items in survival tab of creative inventory. How to reproduce - place item to first 5 slots in row and item will appear in other slot in same row. Trying to wear armor also will duplicate it.KosMos pv 15:22, 24 July 2012 (UTC)

[X] [Cr] Also in the survival tab of the creative mode inventory, items in the later slots in the row will appear 4 slots to the left and one row down in the inventory, overwriting any items that were there before. pretends2bnormal 14:31, 24 July 2012 (CST)

[X] [Su] When the player right-clicks a stack of buckets to fill them, the number of buckets in the stack will not decrease until only one empty bucket is left. The buckets do not duplicate, it's just a graphical glitch. Elhessar 22:28, 24 July 2012 (UTC+1)

When attempting to use a stack of melons to fill hunger, the hunger bar does not increase but the entire stack is consumed. Yuki-nagato 21:37, 24 July 2012 (UTC)

World Generator

Bugs

[X] When generated a new world this happend: http://imgur.com/qpysV,0iGz8 http://imgur.com/qpysV,0iGz8#1 - Emiel071

  • Testing now. --Nathan2055 15:52, 24 July 2012 (UTC)

[X] Leaves can sometimes generate over bonus chests thus breaking the chest. --LightTrench 19:55, 24 July 2012 (UTC)

Mobs/NPCs/Animals

Bugs

[X] mobs still fall trough the ground a lot. mostly npc's who sink halfway through the ground. Please fix this before 1.3. take your time.--League 19:16, 24 July 2012 (UTC)


[X] Angry Wolves spawned from Custom/Modified Monster Spawners (wolf spawners that spawn wolves with an Anger tag of 1) will not attack the player unless the player attacks them first, rather than being auto-aggressive/hostile as angry wolves created normally (by hitting a wolf) are. This is regardless of the difficulty or gamemode. --AnotherMinecraftLP 15:48, 24 July 2012 (UTC)

Annoyances

[A] Iron golem some what walk slower. --superluis1 16:23, 24 July 2012 (Us time)

[A] Deletion of trades by villagers results in the inability to generate sufficient quantities of emeralds to open up new trades. For more details, see this forum thread --Exasperation 21:43, 24 July 2012 (UTC)

Fixed/Skipped

Graphical/Lighting

Bugs

[!] [MP] Sometimes upon respawn the player who died will not be able to see other players, or vice-versa. Reconnecting to the server fixes the issue. --Ningamer 15:17, 24 July 2012 (UTC)

[X] Inverted slabs with blocks above them STILL have incorrect lightning... (Screenshot) -- Mustek 14:30, 24 July 2012 (UTC)

[X] I have two PPC macs. One with a 9200, one with a 9550. In the past (1.0/1.1), the 9200 was too slow to be playable, and the 9550 was barely playable with optifine. In 12w30_b_, both machines are playable, and the 9200 gets better frame rates than the 9550; the 9200 has some graphical glitches, but the better frame rate makes up for it. The 9200 seems to be trying to do less. I'd like the option to have my "better" card do less as well. (Mac mini, 9200; iBook G4, 9550.) http://www.minecraftforum.net/topic/1371155-12w30b-snapshot-ready-for-testing/page__st__160#entry16728430 --Keybounce 17:57, 24 July 2012 (UTC)

Sounds

Bugs

[X] Rain Sounds often don't play in Extreme Hills Biomes below y=90.

  • This bug is also present in 1.2. --Nathan2055 17:35, 24 July 2012 (UTC)

[X] I have roughly a 50% failure to start up the sound system on minecraft start. System: Macbook pro, Feb 2011 model. Error message reports a failure to acquire a write lock. --Keybounce 18:58, 24 July 2012 (UTC)

  • This bug appears in 1.2.5 if you update LWJGL, and i heard that 1.3 was supposed to update it automatically. There may be some changes in the code between versions of LWJGL. I am on a 64bit Windows PC. --Acomputerdog 21:08, 24 July 2012 (UTC)

Annoyances

[A!] [MP] Footstep sounds and possibly some other sounds like splashing into water - eating are delayed depending on the player's ping(server-sided) which is really annoying(This was in the older snapshots too) --Crashty

Fixed/Skipped

Menus

Bugs

[X] After leaving the Multiplayer menu, the thread that scans for LAN servers does not get interrupted and sits there running (until a LAN server is found?). It is attempted to be interrupted, but it is in the middle of the scanning process and it waits until it gets a response as there is no timeout on the scan. This was observed in 12w26a, however I have not noticed it getting fixed in the changelogs since and figured I'd put it in this page so it gets noticed as I'm sure the 12w26a page isn't going to be looked at now. Better that it gets double checked than not noticed at all. Especially since the 1.3 release is in a couple days, no?

[X] The Multiplayer menu freezes when clicking "Join Server" for a couple of seconds, sometimes even 15 seconds.

In-Game Interfaces/HUD

Bugs

[X] When you take a screenshot and open chat in multiplayer, then click the screenshot name, Minecraft treats it as a link. Pressing Yes in the dialog that follows, will cause your web browser to open the link, without any http://, https://, file:/// or any other prefixes. Only applies to multiplayer, since singleplayer can't open chat. Screenshot

[X] You can't enchant anything between 21-29 levels with 15 bookcases. - ScreenshotxPaw at 13:23, 23 July 2012 (UTC)

  • You don't have 30 points, just 26 according to your screenshot. --80.134.11.177 14:56, 23 July 2012 (UTC)
  • I think he's trying to get the enchantment table to give him an option that takes 21-29 (ie, 26). It's giving him 20 or less and occasionally 30. Getting 30 proves that he has enough bookcases and should get (many) options in the 20s. --5thHorseman 15:52, 23 July 2012 (UTC)

[X] The sprites for both kinds of porkchop, steak and raw beef are not aligned with each other, even though they share the same shape. Redstonehelper 12:55, 24 July 2012 (UTC)

[X] In the Creative inventory, the right-most slot in the hotbar in the inventory overlay on the Survival tab is different than on all other tabs. To pinpoint the offending pixel more, compare the top right pixel in those tabs. It shouldn't be as bright as the pixels directly underneath it. Redstonehelper 12:55, 24 July 2012 (UTC)

[X] In the Creative inventory, in the survival tab, dragging items from the quickbar to the inventory duplicates said items, sometimes overlapping existing items. tbfdm

[X] Turning clouds off and then changing the GUI scale in Video Settings to 'Large' or 'Auto' will cause clouds to toggle on again. Ningamer 15:03, 24 July 2012 (UTC)

[X] (30_B_) Multiplayer, with "NoGui", using the terminal window to issue commands:

1. You cannot use "seed" to get the world seed -- it wants you to use a player.
Turns out, even if you say "seed keybounce", it still responds "You must specify which player you wish to perform this action on". I figured at first that this was just to permit the end, or the nether, to have a different seed than the overworld, but even this does not give the seed to where it can be copied/pasted.
2. If you type ctrl-D into the window, then the server stops reading commands from the keyboard. But the server keeps running.

--Keybounce 19:33, 24 July 2012 (UTC)

Annoyances

[A] Now that the other wooden stair types has been added, the "Building Blocks" section needs to be reordered, also Oak Wood Stairs needs to go right before Spruce Wood Stairs. Image: http://h9.abload.de/img/2012-07-05_19.05.556px8y.png

[A] Skin changing takes a long time to update in this snapshot, whereas as before all you had to do was reopen Minecraft for your new skin to appear.
