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

?! When I enter my password and I select Remember Password, the next time I log on i have to reenter my password. I haven't noticed this in previous releases.

!! My Minecraft (Unmodded 1.2.4, no tex packs) randomly crashes with a "saving Chunks" error then goes to black, no error report. What the...? - 1Samario1

a! mp After executing a command in the text entry box, Minecraft will not exit entry box thus stucking the player in talking mode. Entering another command or text will on a few occasion give the opportunity to exit text mode. In most cases anyway, it will write another line beginning with a slash. This deprives the player from using command such as /tpa, /home or faction related command. This did not occur before 1.2.4. !! mp When deleting a long string of characters from the text entry box, Minecraft crashes upon deleting the last character, or perhaps as it tries to delete the last character. The number of characters are irrelevant, but must be long enough such that the length of the message exceeds the visible space in the chat box. Ex: Typing 71 'w' characters, then deleting them will cause Minecraft to crash. (tapping backspace once more after deleting all the characters may be required to reproduce)

!! mp With the in-game chat active, when holding the up arrow to scroll through all your chat entries, Minecraft will crash to a black screen. This only happens when there are a lot of chat entries to scroll through. - d3fin3d

 * This happened to me. I made a new world in creative and the game crashed before I even got a chance to spawn.  I re-entered the world and flew around until 10 minutes later when a Saving Chunks screen appeared followed by a crash.

Fixed/Skipped

Minecarts/Boats
Bugs undefined 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

undefined 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

undefined 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

 * 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)

! 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 and maybe earlier, please fix ! (SMP, Linux 64 bits)

! 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, but happens often. Very important bug, exists since 1.1.0 (see the 1.1.0 known bugs to reproduce, but I don't known if it is the only way to produce it), please fix ! (SMP, Linux 64 bits)

undefined Pressure Plates (at least stone, not tested with wood) can stay in the ON position when no entity is on it. I've watched them press themselves down after being previously in the OFF position. (Looks as if an invisible entity is pressing it down while walking)

undefined An open trapdoor will be closed when a normal torch (not redstone torch) next to it gets destroyed. --ReLuLu

Annoyances

a Redstone repeaters increase the length of short pulses(one to three ticks) of power. When the delay setting on a repeater is a larger number of ticks than the incoming pulse, the outgoing pulse is increased to the length of the delay. Can be reproduced using a one-tick pulse generator followed by a series of five one-tick repeaters. Then change the delay on the first repeater in the series of five to the desired pulse length. If repeaters only delays the incoming signal, then the outgoing pulse should be the same length as the incoming pulse. It would be useful if this behavior was mentioned on the redstone repeater page. --76.227.102.45 02:49, 25 March 2012 (UTC)

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.
 * Would mojang release a 1.2.5 to fix this?--MCKMan
 * I wouldn't expect to see a 1.2.5 at all unless a super-urgent crash bug is found. My fingers are crossed to see all these recipes in 1.3, though. Inability to craft wooden items out of all the available wood types is certainly a valid annoyance in a game that's largely about architectural design, and I can't imagine adding a recipe for a known block type using already-existing ingredients is more than a few minutes work. (Though if Jeb or Dinnerbone or one of the others would like to correct me, I'm always interested to hear about the nuts and bolts of other peoples' games.) --72.208.204.70 08:46, 23 March 2012 (UTC)
 * Wooden Planks save their type in data and need two bits for that. Every wooden item would have to be rewritten in order to use this data too, and I'm not sure whether all wooden blocks still have two data bits free (doors, stairs etc. may store other things there). --GALAKTOSTalk – ceterum censeo error quasi-connectivitatis pistonis delendam esse. 19:30, 23 March 2012 (UTC)
 * There's plenty of block IDs available now. Any block that already uses the data bits (such as stairs) could simply have four separate block IDs. I feel that it's worth doing, as the new wood colors are a lot less useful if we can't get the stairs/slabs/etc. that we use as trim and ornamentation in matching colors. --72.208.204.70 20:18, 23 March 2012 (UTC)
 * As a side note, this would also be an opportunity to fix the problem where wooden slabs don't chop like wood: one block ID for wood slabs, another for regular slabs. --72.208.204.70 19:33, 24 March 2012 (UTC)

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 Placing one block frequently places two when having only clicked once.
 * Maybe it's your mouse. I've experienced this multiple times before, and changing the mouse fixed it until that one went out. 72.251.53.167 13:06, 24 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)
 * Sounds to me like it's just your keyboard. Do you ever get repeated characters when typing text on it? --72.208.204.70 08:30, 23 March 2012 (UTC)
 * It's not just their keyboard. This happens for a ton of players, including myself. It's probably the most prevalent bug for me, but Mojang is aware of it, and what causes it. Apparently, Minecraft uses a heavily outdated version of... something-or-other... ( LWJGL 80.134.7.215 )which causes this issue. Jeb wants to update to the newest version of that something-or-other, but he didn't have time to do that for 1.2.
 * Interesting! Thanks for the info.

undefined When crafting a map, using the shift-click to automatically move the map into the inventory, instead of creating a new map, a duplicate of a previous map is made, regardless if said previous map is in the inventory. Although in a way it is useful creating duplicate maps, it is certainly a bug.
 * Was able to reproduce, but only creating the map for the first time in that world. Did not work afterwards, even with no map in inventory - DaemoN67.

undefined Sometimes when you press F11 and switch between windows "Back to Game" button will only work from second click (possibly other buttons too) --Trinistr 05:48, 25 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.

a Sneak mode only protects against moving off the edge of a block. Could it be expanded to prevent you from entering a same-level lava tile? 82.69.54.207 00:58, 24 March 2012 (UTC)

a Like previous version, position for center of screen is miscalculated in full screen mode, when using a menu (crafting table, inventory, brewing station etc...)

a Mushroom stew still doesn't stack.

I can confirm that it was working in 1.2.3 --Killerog 13:50, 24 March 2012 (UTC)
 * How do you stack Mushroom Stew in reality without pouring it out? Or Soup? Or Cornflakes? Why shoud work that in MC, when it's incredible in reality? It's not a bug and also not an annoyance!--Locoloco 09:52, 24 March 2012 (UTC)
 * Because Minecraft is the epitome of realism. A more feasible explanation is that with the addition of giant mushrooms, it's incredibly easy to get lots of mushroom stew. So if you could stack it, one could have tons of a reliable food source to carry around with very little effort.
 * Drop the bowl after eating it. Then Mushroom Stew can be stackable. HotdogPi Come to my page! 14:55, 24 March 2012 (UTC)
 * Works fine for me. I am on an SMP bukkit server, and it crafted with no issues. ~DaleK 16:50, 24 March 2012 (UTC)
 * I tested further, and the snowballs I used were spawned. If picked up from the ground they don't craft. However, snowballs obtained before 1.2.4 work fine. It is as if 1.2.4 generates/changes snow cover blocks to drop a different meta data of snowball or something, and that is why they cant be crafted. If a spawned snowball is in the inventory, and you get more snowballs, then they don't stack. But if you manually combine the stacks, then even 1 spawned snowball with the rest, craft a snow block. The new snowballs are very strange, and I hope they can be fixed. ~DaleK 21:44, 24 March 2012 (UTC)
 * Can't reproduce. I've just shovelled up some fresh snow and crafted snow blocks out of the snowballs with no trouble. Also spawned a few snowballs, and they stack with the natural ones and craft blocks normally. --72.208.204.70 04:03, 25 March 2012 (UTC)

 * By the way, this bug has been fixed in CraftBukkit since a while, so it shouldn't be difficult to fix that. =)

x  doesn't work, so we can't see the Players List (until we change it to another key) or type the beginning of a username then tap  to autocomplete it.

x cr Now, if the inventory is full, we can still pick up dropped items. It's annoying if we want to move a double chest with all its content. --Gimlao 15:53, 24 March 2012 (UTC)

Now we can pick up all the items, but it will destroy the excess in the player inventory.
 * Simple fix, only destroy one chest instead of two at a time. Or just take note of whats in the chest are replace it with your infinite inventory of everything. ~DaleK 16:54, 24 March 2012 (UTC)

x When the game searches for an existing portal (going from the Nether to the overworld), it doesn't seem to check above height 128. (Created a portal in the overworld at Y: 151, entered it, went back into the resulting portal in the nether, and ended up in a new portal at ground level) I think that problem is coherent with the problem that the Nether still goes from 0 to 128, above is just air!--Locoloco 10:35, 24 March 2012 (UTC)
 * Reproduced!!! But you can reproduce it even the other way! Building a Portal in nether above 128 (still a Bedrock-Border!!!) create a Portal in overworld at Ground-Level. Going back through the same portal end at the first nether-portal wich was created in the map.

a! su Half wooden slabs have to be collected with a pickaxe and will not drop anything with an axe.
 * Possible solution: make wooden slab it's own block, which doesn't share block id with other slabs — MiiNiPaaT
 * Wooden stairs collect faster with an axe than a pick, so they could just duplicate what they did there. -Sennyotai
 * Wooden stairs are completely different block from others stairs. Now there can be more than 256 block types, so no need to save block ids. — MiiNiPaaT

a! Major lag spikes when I turn around quickly. It starts happening after about a minute of loading the world and walking around a bit. This didn't happen in 1.1 with the same graphics settings.

NPC/Animals
Bugs ? mp: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.
 * You sure it isn't just the chickens drowning in the water flows? I noticed awhile ago that they have trouble rising up out of flowing water. (My case was sending them up a watershaft with the top as a flow. They would invariably drown because they wouldn't swim up above the flow.) Its also not uncommon for a chicken in an 'egg-cell' (chickens in closed area swimming in water suspended by a sign) to drown or just die randomly from the chickens forcing each other underwater. - Sennyotai

undefined 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:


 * Confirmed that this happens in both single and multiplayer survival.

undefined I have a large warehouse in an NPC village, inside of which Golems sometimes spawn (because of the skylight, I assume, although the villagers still consider it a 'house' worthy of being crammed into at night). The floor is made of upside-down slabs, with a basement below. When golems spawn inside, they are unable to move (except rotating), and quickly snap back when pushed. More annoyingly, though, they are also unable to be attacked. The only way to kill one is to remove a nearby floor slab, go down into the basement, and attack the golem through the hole in the ceiling. Some sort of hitbox/collision detection problem? --72.208.204.70 08:27, 23 March 2012 (UTC)

A Villagers seem to be reproducing way too much, I have a home in a village and it is packed with childern. At night houses are crammed and during the day it's hard to get around.
 * I definitely had this problem in 1.2.3 multiplayer. Had to slaughter the village every now and then, because the population limit simply doesn't work. Killed them all again just before the 1.2.4 patch though, so it'll be a couple days before I can see if it's still happening to me. --72.208.204.70 22:08, 23 March 2012 (UTC)


 * I had this problem too. I had to cull an entire village to prevent my game from lagging out.  It may be a problem with how the villagers interpret house and village size, and maybe aren't recognizing a limit to their population like they should.

a If cat is sitting on a chest and you take out raw fish, cat will stand but it will not do anything else (which is disappointing). --Trinistr 08:35, 24 March 2012 (UTC)

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"

undefined Snow golems will not produce snow in a number of biomes: Swamps, plains, and mushroom lands. This seems to be unintended. Also, snow golems would be killed by falling snow in the last patch, because the snow was counted as rain. I'm not sure if this has been fixed yet.

Annoyances

a! New lighting system severely drains FPS since 1.2. This is still apparent in 1.2.4. Lighting changes in-game caused by lava, redstone lamps, redstone repeaters and/or pistons cause heavy FPS drops on low-mid range computers. This problem didn't exist in any version prior to 1.2. It looks as though there is now a lot of excess load on clients to calculate lighting changes, whereas pre 1.2 Minecraft forced the server to deal with lighting calculations. This essentially makes the nether and busy piston/redstone contraptions unplayable as the FPS lag is extreme. d3fin3d


 * I can confirm entering the nether negatively affects my framerates compared to pre-1.2. Often while entering at the level of a lava ocean my framerates drop to the 35 - 50 range. Outside of the nether I can get upwards of 200 fps (though 120 is average ). DarkWolff 14:17, 23 March 2012 (UTC)
