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)

Gameplay

Bugs

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

[!] 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 from another bug report) 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 from duplicate bug report) 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] 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)

[N] 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)

Blocks

Bugs

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

[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 from duplicate report) 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)

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

Mobs/NPCs/Animals

Bugs

[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)

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)

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?

In-Game Interfaces/HUD

Bugs

[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] Skin changing still does not work, you will always retain the skin you had at the time of the snaphot's release. Getting a new .jar and even force updating don't fix this bug.

[X] Shift-clicking glass bottles into a brewing stand puts all of the bottles into one slot. This cannot be done manually, only by shift-clicking. Elite6809 (talk) (forum) 17:56, 24 July 2012 (UTC) ~Nevermind, you don't put glass bottles into stands anyway, you put water bottles
