[edit] Organization of This Page & Instructions

When reporting or commenting on a bug or annoyance, please sign your remarks with ~~~~. This is a deliberate exception to the usual wiki conventions; normally you should only add signatures to content on talk pages.

Please do not spontaneously delete an issue report or comment unless it is patent nonsense submitted by someone who has not logged in. Try to contact the submitter by user-talk first and tell them about your concerns. Almost all genuine, active submitters will be co-operative. 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 latest version (for this page, that's 0.3.0 Alpha for iOS and Android). 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] .)

Please make sure issues are given the correct category, type, and priority: redstone issues go in the Redstone section, problems with mobs go into the Mobs section, and so on. List crash bugs [!!] first, then major bugs [!] , then minor ones [X] . Annoyances go into the Annoyances subsection, with major ones [A!] before minor ones [A] . Issues that have been marked as fixed or skipped are moved to the Fixed/Skipped section. Issues that Mojang cannot reproduce should be left 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.

Note: Please don't let debates about whether something is or is not a bug or annoyance get out of hand. Similarly, don't clog bug reports with discussions of workarounds or possible fixes. If ever a bug or annoyance ends up with more than about 10-12 lines of follow-up comments, please move the entire follow-up discussion to the talk page and put in a cross-reference to the discussion under the original bug.

[edit] 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 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}}.

[edit] Crashing/System

Bugs

• [!!] when loading a world with lava it will light ALL blocks on fire except bedrock and will not stop unless all blocks except bedrock are gone. due to all blocks being on fire the game will lag very much and possibly crash due to to much things happening at once in-game

• [!!] When selecting a world, after selecting a world, if you select back quickly, the game will load behind the menu, and if you try to start a new game, it will crash. This can be fixed by restarting the app.^{[Tested on iOS only]}

• [!!] The game freezes when loading a world with most it at a low elevation, for example, a flatgrass map with ground level at Y=32.

• [!!] Sometimes after the Mojang logo appears or loading any world, the app will display a white screen and it freezes for some seconds, sometimes this will restart the app.

Annoyances

Fixed/Skipped

[edit] Blocks

Bugs

In CMP, if you place a torch on top of a block, it will be placed on the side of an adjacent block, and if that block is removed the torch will stay there in midair. (Tested on CMP, iOS)

[X] If you cut birch and/or pine trees leaves with the shears, instead of dropping leaves, sometimes it will drop a weird textured crafting table. When picked up, in your inventory, you will, see the leaves, with the correct texture (They are not stackable). Some times they will appear like they are infinite. When you put it in your hotbar, they'll have the durability green bar, but it doesn't decrease. If you place them, and then break it with the shears again, you will get the non-glitched leaves. [Tested on Android, iOS,Tablet]

[X] If you hold down on the invisible bedrock that surrounds the map, it creates particles as if it were bedrock.

[!] When you break wooden/stone stairs, instead of dropping the correct block, it'll drop wood/stone blocks respectively. This causes one free block when making stairs, because to make 4, it only requires 3 blocks. [Tested on Tablet]

[X] when you create a book shelf and place it down. you get three bookcases back when you destroy one normal bookcase. so this a duplication glitch which I found rather funny. as you could build a house out of bookcases . tested on ios5
