Minecraft Wiki:Issues/1.2.4

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 1.2.4) 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). (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 aspmpsucr.)

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  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)
 * !! =  !!  = Critical bug that can crash a Minecraft client or server.
 * ! =  !  = Major bug. Use this tag sparingly; if there is consensus your bug is not major, it will be downgraded.
 * a! =  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.
 * undefined =  undefined  = Minor bug.
 * a =  a  = Annoyance.
 * ? =  ?  = 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 =  sp  = Single-player.
 * mp =  mp </tt> = Multiplayer.
 * su =  su </tt> = Survival mode.
 * cr =  cr </tt> = Creative mode.

Labels for indicating that an issue is restricted to a particular OS:
 * =  </tt> = Mac OS X
 * =  </tt> = Windows
 * =  </tt> = 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:  </tt>c </tt> 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  undefined </tt>.

Crashing/System
Bugs !! Creating a new world in creative mode gives a black screen. Reloading Minecraft makes the new world available - Lucifer_LLS 17:59, 22 March 2012 (UTC)
 * Second time I have posted this, someone removed it for some reason
 * Not getting this error --Sejsel 18:06, 22 March 2012 (UTC)
 * Neither am I. --[User:Sanoth|Sanoth]] 18:18, 22 March 2012 (UTC)
 * Unable to reproduce this too. Any error log or cmd report? -EvilSeph 18:49, 22 March 2012 (UTC)
 * No error log, Minecraft just sits on a black screen until you close it. Happened on two different machines both running Windows 7 Pro 64Bit with latest Java 7 - Lucifer_LLS 18:55, 22 March 2012 (UTC)
 * I have Windows 7 Ultimate 64 bit, Java 6. Unable to reproduce. I bet this is a java 7 issue.
 * Upgrading to the newest Java is not always the best idea. Try it with Java 6 and report back
 * Unable to reproduce. With Windows 7 Pro 64Bit, Java 7. Maybe you're also naming the worlds something in particular, or have certain security settings? 69.116.205.16 01:06, 23 March 2012 (UTC)
 * Tried even on a fresh install of Minecraft. I do have Java 7 JDK installed rather than just JRE. Does MC use the server compiler if its available? Maybe that's the difference - Lucifer_LLS 01:29, 23 March 2012 (UTC)

Minecarts/Boats
Bugs c When a boat pushes a boat, water particles can be produced even if the boat is on land. This can also be accomplished by attempting to shoot a boat back while sprinting. Cactose

c When a boat is placed close enough to a block, the boat will be partially in the block and often makes no attempt to get out. The boat can then be pushed further in. Cactose

c Getting into a boat with a water or lava bucket in hand causes the contents to be dumped if there is a selectable block on the other side of the boat. Cactose

mp When crashing a boat, the usual wood and sticks drop. However, a minecart also drops with it. Breaking it the normal way, produces the normal drops [no minecart] This hasn't been tested in Single Player yet. KHRoxas

Annoyances a Boats do not clip properly on their diagonal sides and can be turned on an angle so they move into blocks. Cactose

a Boats do not clip properly into slabs. Cactose

Redstone/Pistons
Bugs

u when press "F2" will crash your game or in "F1" mode (unless it was my pc but i have never had that in minecraft)
 * Unable to reproduce, can take screenshots just fine here. Any error or cmd report? --EvilSeph 19:25, 22 March 2012 (UTC)
 * Won't be able to reproduce due to OS upgrade but this used to happen on Java 6 on a 32bit XP Machine for me - Lucifer_LLS 01:32, 23 March 2012 (UTC)

undefined Redstone repeaters can freeze. Appears in loop circuits, the input at 1, the output staying at 0. It seems to involve game reloading / disconnect and reconnect. A way to restart the circuit (it will eventually freeze again) is to remove the input redstone wire and place it again. Or anything that causes the input to be updated. Very important bug, also existed in 1.2.3, please fix ! (SMP, Linux 64 bits)

undefined While functioning (does not involve game reloading or anything), pistons can place themselves in a state simultaneously exended and not extended. This state never changes until the extended block is broken by hand, which restarts the circuit. This happens only for certain designs. Very important bug, also existed in 1.2.3, please fix ! (SMP, Linux 64 bits)

Blocks
Bugs undefined Under wooden slabs a strange shadow seems to appear even in a well lit room, appears to be visible to all of the players on SMP. Crashdoom 01:53, 23 March 2012 (UTC)

Annoyances a Walking over slabs placed on top of Ice blocks causes you to slide as though you are walking on the ice blocks. --Vikhedgehog a It is not possible to place a torch on the back face of a stair or on a 'top' slab.
 * Corrected grammar for clarity.
 * And I fixed your grammar.
 * Sounds more like a bug than an annoyance for me.
 * It's not a bug, it's a feature.

a! Recipes are needed for Circle Stone Bricks and seamless smooth Stone Slabs.

a Recipes are needed for stairs and slabs in the three new wood colors. Colored Fences and Bookshelves would also be nice.

a To bring the slab/stairs groups into parity, recipes for Netherbrick Slabs, Sandstone Stairs, and Stone Stairs (matching the smooth slabs) are required.

a I would also like Glass stairs and slabs. And cheese. And cheese sammiches. And a pony. And... --72.208.204.70 22:42, 22 March 2012 (UTC) Fixed/Skipped

Crafting/Enchanting/Brewing/Interface
Bugs a!mpWhen you press Tab key to complete someones name and hit enter you get kicked for illegal character.

a! mp Links get cut off if the URL goes onto a new line, some people apparently don't notice it too... Crashdoom 01:59, 23 March 2012 (UTC)

undefined When dragging the corner of the window to expand, if you have something typed into chat it is erased.

undefined The second new Sandstone-Block cannot be crafted, the other new in a 2x2 Crafting Grid gives four of itself: Link to a Picture --Galaxy_2Alex (Talk)


 * Put one sandstone slab over the other in the crafting grid to get the hieroglyphic block. DarkWolff 17:21, 22 March 2012 (UTC)
 * One slab above the non hieroglyphic one? --Galaxy_2Alex (Talk)
 * Oh no, I found the mistake, thanks --Galaxy_2Alex (Talk)
 * The behavior of 4 of the smooth sandstone producing 4 smooth sandstone is because 4 of any sandstone in that configuration will produce that. Similarly, any three sandstone can be turned into the ordinary slabs. Because of this, you can effectively convert freely between smooth, hieroglyphic, and slab sandstone, with no material loss or gain. Personally I think it should be kept this way.

f We can't open links without "www" at the beginning.
 * Impossible to open "et6.free.fr" or " http://et6.free.fr/ " for example, the second one isn't even clickable.
 * For info, " http://et6.free.fr " without a "/" at the end works.
 * Moved from System/Crashing --Galaxy_2Alex (Talk)
 * Thanks, I was minding if I should have placed it here or not. Gimlao 18:51, 22 March 2012 (UTC)

? Every now and then Steve randomly lurches a couple of paces of his own accord. This may cause him to step into lava or accidentally walk off a cliff. Usually happens just after you've moved him yourself, as if it's a keyboard lag issue. Occurs rarely, once or twice an hour of play - so you're never entirely sure it wasn't your own fault, but I've started watching for it and am pretty sure it wasn't me. Seen with a USB wireless keyboard with old-ish batteries. Not seen (yet) with alternative Bluetooth wireless keyboard I also have. 82.69.54.207 23:10, 22 March 2012 (UTC)

Annoyances a In all the item container windows, if you try to swap the same type of items, it does not work. You have to use another slot to make 3-step swap. People have told me it is so since beta 1.7, but as there is no bug tracker database, I will submit it here to catch attention (hopefully)
 * Example 1: one iron sword against the one with different durability (works only in case when one is enchanted but other is not),
 * Example 2: two blocks of stone with different stacked amount.

a "Large Chest" is missing from the language file (always English only). Looked into the crowdin, it is not listed there either. Fixed/Skipped

Gameplay
Bugs u cr Unable to place mushroom in creative mode
 * Can't reproduce. Please know that mushroom placement behaviour was changed in 1.2.4 - it needs some darkness.

a! su Half wooden slabs have to be collected with a pickaxe and will not drop anything with an axe.

a! su If the ground within one block of a piston that is being powered by a redstone torch facing upwards is hoed it will retract.

Annoyances a in SMP, you can't use enderpearls to perljump in gamemode 1.

NPC/Animals
Bugs ? There is a possible collision bug that kills entities forced onto the same block by the flow of water. It can take some time before the bug reveals itself. I have created a imgur photo album with more detailed descriptions on how I came across this bug while creating a chicken hatchery (imgur album link): * Please note that I've only tested this with chickens and only on SMP.

undefined sp Nearby (100-200blocks) dogs/cats teleport to you, even they are seated.
 * Specifically I've noticed that previously sitting cats and dogs teleport to you as soon as you get in range.


 * I tried reproduce the bug in a new world (generated in 1.2.4). No problem with this. Maybe a bug with converted worlds (pre 1.2.3).


 * Another case:

Annoyances a The new cat behavior is cute, but having to break a (potentially full) chest is too annoying to be fun. Suggestion: right-clicking such a cat several (4+d6?) times (simulating petting) causes the cat to stand and resume normal behavior. Fixed/Skipped

Mobs
Bugs ! sp On some worlds, mobs will either spawn at a ridiculously low rate or not spawn at all, even on Hard difficulty. Reloading the world and changing the difficulty back and forth from Peaceful to Hard occasionally fixes the issue, but only for less than a minute. It seems like this could be linked to an old bug where mobs would get "stuck" in a half-unloaded state outside the 144-block spawning radius, where they take up spots for other mobs to spawn but don't despawn on Peaceful until you approach them. This doesn't seem to fully account for the issue, though, since I've walked around on Peaceful despawning these glitched mobs and the problem relapses again after only 30 or so seconds. It's really strange and game-breaking to have no mobs at all on the surface during the night, even with all the caves in the area lit up, and this has effectively wrecked my game experience in this world. --Voidzm 18:08, 22 March 2012 (UTC)
 * had this also, occurs above lvl127: no spawn at all in the dark room (mobtrap), fix is: remove and replace torches that are placed above the "dark room"

Graphical/Lighting
Bugs

x mp Glowstone sometimes doesn't light up chunks in SMP, allowing mobs to spawn in the area. Example: http://img215.imageshack.us/img215/1117/glowstonebug.png Walking into the dark area generally causes the light to update (but not always), but logging out and back in reverts it. The same chunks seem to be effected. Putting torches in the area works as a band-aid however. DarkWolff 17:29, 22 March 2012 (UTC)

x mp Digging a one block hole in the ceiling and putting a torch in it shows a dark spot, though the torch still produces light below. Example: http://img820.imageshack.us/img820/8858/oneblockhole.png DarkWolff 17:29, 22 March 2012 (UTC)
 * Same thing with a lever. Gimlao 00:20, 23 March 2012 (UTC)

xmp TNT in multiplayer still produces ghosts. 

xmp The Skyligh in multiplayer still does not compute correctly. Blocks still appear to be lit up, even when within a completely closed room. Walking on, or updating the block seems to sometime fix the issue. But it sometimes returns to the same block

xsp Extended piston shafts do not light up from non-sunlight light-sources. Cactose

Sound
Bugs Annoyances a mp when the volume is turned up and you play a record, if you then turn the volume and SFX down, the record will continue to play, even if removed from the record player.

a A continuing issue from many versions back - Extreme Hills biomes have silent rainfall. Rather jarring when flying around, but not quite at the level of a bug (hence, it's still an annoyance). Fixed/Skipped

Language
Bugs undefined mp The ` symbol will show up in your text bar in the chat window, but once you hit Enter and send the chat, it shows up invisible on the chat window for you and other players. Discovered in Language: English (US) and seems to be an issue in any Language. Annoyances a In 1.2.4 the Greek Language option says "Αγγλικα" which means "English in Greek", not "Greek" which is "Eλληνικά" Fixed/Skipped
