Organization of This Page & Instructions

Please do not spontaneously delete an issue report or comment, unless it is patent nonsense submitted by someone who has not logged in. If possible, contact the submitter by user-talk first and tell them about your concerns. They will almost certainly oblige. As always, assume good faith.

If you're unsure of an issue, it's good practice to post about it on the talk page to see whether others can reproduce it. Make sure you're testing the bug in the correct version (for this page, that's 1.2 Preview) with no mods installed. Also, make sure to proofread your issue report before submitting it; unintelligible issue reports come off as inconsiderate and disrespectful. Finally, please determine which game mode(s) your issue appears in, and flag it with the appropriate label(s).[1] (Also, note that if, for example, a minor annoyance appears in both single-player and multiplayer, and in both creative and survival modes, you should label it as [A] , not [A] [SP] [MP] [Su] [Cr] .)

Be sure to sort issues by category, type, and priority: redstone issues go in the Redstone section, etc.; bugs go in the Bugs subsection, with major bugs listed before minor bugs, annoyances in the Annoyances subsection, with major ones before minor ones, and issues that Jeb has marked as fixed or skipped are moved to the Fixed/Skipped section. Issues that Jeb cannot reproduce, however, are to remain in their original place.

Please sign all issue reports and comments by typing ~~~ (three tildes; tilde may be found above Tab ↹ on USA keyboards, and to the right of @ on British keyboards).

There is no need to place bullet points before issue labels. Use bullet points only for comments. Be sure to leave a single totally blank line before each new issue (but not before comments), unless the issue appears directly beneath a header.

Issue Labels

Please mark your issue with one of these issue labels: (listed from highest priority to lowest)

  • [!!] = {{bl|!!}} = Critical bug that can crash a Minecraft client or server.
  • [!] = {{bl|!}} = Major bug. Use this tag sparingly; if there is consensus your bug is not major, it will be downgraded.
  • [A!] = {{bl|a!}} = Major annoyance. Think very carefully before flagging an annoyance as major. Is it really more important than most minor bugs? Use this tag sparingly; if there is consensus your annoyance is not major, it will be downgraded.
  • [X] = {{bl}} = Minor bug.
  • [A] = {{bl|a}} = Annoyance.
  • [?] = {{bl|?}} = Potential issue that you are unsure of or that the community (on the discussion page) believes requires further vetting. Note: do not use this label to indicate this-is-not-a-bug; instead, replace the issue's current label with [A] or [A!]. Furthermore, it is inappropriate to use this to flag something you disagree with; instead, express your opinion in a comment. When you apply this label to an issue, place it after the issue's existing labels; do not remove those labels.

Labels for indicating that an issue happens only in a particular game mode: (These labels cannot stand alone; you must use them in addition to, not instead of, the ones listed above.)

  • [SP] = {{bl|sp}} = Single-player.
  • [MP] = {{bl|mp}} = Multiplayer.
  • [Su] = {{bl|su}} = Survival mode.
  • [Cr] = {{bl|cr}} = Creative mode.

Labels for indicating that an issue is restricted to a particular OS:

  • macOS = {{OS|OSX}} = Mac OS X
  • Windows = {{OS|Win}} = Windows
  • Linux = {{OS|Linux}} = GNU/Linux

Labels that Mojang (not you!) uses: (Please place these tags in front of existing issue labels; do not remove the existing labels.)

  • [F] = Issue for which a fix will appear in the next update.
  • [N] = Not a bug; intended behavior. By definition, this label is inapplicable to annoyances; annoyances are not bugs.
  • [S] = Issue that will not be fixed in the next update.
  • [U] = Issue that Mojang has tested but was unable to reproduce.

To produce these labels, use the following code: {{bl|c}} where c is the code of the label you wish to use. (e.g., a for annoyances, etc.)

The default issue type is minor bug; you can produce this label with the shorthand {{bl}}.

Crashing/System

Bugs

[!!] [SP] [Cr] Created a single column of Glowstone up to 256, and got a "saving chunks" crash, logged back in and it kept crashing, shortened the render distance and still crashed.--Sxerks 17:51, 29 February 2012 (UTC)

[!!] When you go to options and click on controls the game crash.

[!!] [SP] [Cr] Created a single column of stone up to 256 in nether and was able to place lava on to of it and got the "saving chunks" crash, logged back in and it kept crashing.

Annoyances

[A] In the video settings menu when cycling/clicking through the gui scale option, clouds will be toggled on/off.

Fixed/Skipped

Redstone/Pistons

Bugs

[X] [SP] [Su] Piston heads frequently fail to push the player. The same occurs with items. [X] When you stand on upside down slab and push it up by piston, you will fall through the slab.

Blocks

Bugs

[X] [Cr] [SP] When breaking the top half of a wooden door in Singleplayer Creative, the door drops as an item, when you break the bottom half though, it doesn't drop as an item. 90.231.9.197 18:30, 29 February 2012 (UTC)

Annoyances

[A] In 1.2, you added the ability to place torches on top of upside down stairs. However, one cannot place a torch on a upside down half slab, though this makes no real sense. Note that one can place a torch on a double-slab block, and the upside down half slab is at the same level as it is. -otto4242

Fixed/Skipped

Crafting/Enchanting/Brewing/Interface

Bugs

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

World generator

Bugs

[!] Again, Birches and pines spawn rate is very low. --Galaxy_2Alex (Talk)

[!] [SP] Windowsoffline. There is definitely something broken in the biome code since the map heigh is extended at 256. In the normal forest there are no birch trees (I can't find one in about 10 maps in creative) and the trees are all the same height (no big trees). The swamps are broken too, the trees mostly stand in the water, so no mushrooms can spawn. I also couldn't find a pine tree forest. In some snow taigas there were isolated pine trees. The biome generation is not as it was before the extension of height.

Some examples for normal tree forest with same trees and no birches. 6203567990940513874 x:-239 z:256

Graphical/Lightning

Bugs

[X] Mining clay from directly above does not show mining damage texture (cracks) as you're mining it. As seen here: http://imageshack.us/photo/my-images/109/cracks.png/ EsOne

Annoyances

[A] Using the new top-half slabs to create a ceiling causes the undersides of the ones on the inside to become completely black. ~~Minecrafterambesten

[A] In-game maps don't show snow anymore. ~~spiderboy4

Fixed/Skipped

Multiplayer-related

Bugs

[!] Several sound instances do not play:

[!] A few graphical elements are missing:

  • Fishing rod "line".
  • Fishing rod "line" in held item. It shouldn't appear when the line is casted.
  • Other Player breaking animations.
  • Magma Cube animations.
  • Other player's enchanted items don't shimmer.

[!] Mining takes longer in multiplayer than in singleplayer. This is caused by a click-mining 'fix' that was added in Beta 1.3 and is not needed.

[!] Slimes and Magma Cubes randomly warp up and down when they have a ceiling above them.

[!] Knockback and damage screen calculation is often wrong in multiplayer, actually dealing knockback when it shouldn't (like drowning or being on fire).

[!] Hitting mobs is harder in multiplayer because of lag. It is also much easier for monsters to hit players. Probably a delay before attacking (based on lag) should be added...

[!] Anvil's new per-chunk biome data is not sent in SMP. See here: http://wiki.vg/Pre-release_protocol#Map_Chunk_.280x33.29

[!] [MP] Huge Mushrooms planted with Bone Meal are invisible until reconnecting to the server (affects all players on the server)

[X] Player movement is not smoothed enough (the client does this) in fairly or very laggy conditions.

[X] Arrows "warp up" when shot on walls. They also disappear and become impossible to collect when shot on ceilings.

[X] The anti-spam does not really prevent spam.

  • I can type 4-5 messages a second as non-op and I do not get kicked. Calinou - talk × contribs » 23:43, 24 February 2012 (UTC)

[X] Arrow shooting is buggy and sometimes "resets" the charging progress.

[X] The 3 second invincibility on reconnection can be exploited to be invulnerable to falls/lava/PvP/...

[X] Having trouble making tamed wolves change from sitting position.

Annoyances

[A] Instead of saying "Outdated Server!" when going on a 1.1 server, it says:" Internal Exception: java.net.SocketException:Connection reset"

[A] When connecting to an outdated server/client, protocol version/game version should be shown.
