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>.

! 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 You can place blocks in front of paintings. They will (randomly) convert into items after a few seconds. 

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.
 * 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)

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

 * 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 "google.com" or " http://google.com/ " for example, the second one isn't even clickable.

undefined If there are snow tiles between an enchantment table and bookcases, the enchantment table will not become "powered" as normal. Only the lowest-level enchantments will be available, as if there are no bookcases at all. This is probably because the snow tiles are counted as full blocks. Any way to fix this?

? 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.

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),

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.
 * 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

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.

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. The settings are: Graphics: Fancy, Render Distance: Normal, Smooth Lighting: On, Performance: Max FPS, 3D Anaglyph: OFF, View Bobbing: ON, GUI Scale: Large, Advanced OpenGL: OFF, Clouds: ON, Particles: All. This bug kind of ruins survival mode for me, because with so much lag every time I turn around quickly, I can hardly fight against mobs in caves or outside at night.

 * right click and create fire. You can't just hit it. 207.190.166.40
 * You can actually ignite TNT by left-clicking with flint-n-steel, but only in Survival. It doesn't work in Creative, because the TNT block is just destroyed.

a in SMP in gamemode 1, if you are flying fast (like sprinting), pressing SHIFT to descend will exit fast-fly mode.

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)

undefined Baby animals and their parents still become hostile when holding wheat even though they can't be fed. This bug already existed in 1.2.3. --ReLuLu

undefined Endermen can't teleport out of minecarts; however, the "particle trail" to where they wanted to teleport is still shown. (I'm not sure whether it's intentional or not that they can't teleport - it is listed as "Trivia" on their page - but it's definitely a bug that the particle trail is still shown.) In this image the particle trails of two teleportation attempts are visible: one to the upper left and one to the bottom right corner. --GALAKTOSTalk – ceterum censeo error quasi-connectivitatis pistonis delendam esse. 14:04, 23 March 2012 (UTC)

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. --72.208.204.70 04:35, 23 March 2012 (UTC)

a Throwing eggs or snowballs at cats or even punching them doesn't scare them of the chests (or other blocked entities). Only water buckets do the trick.

a The puppy's head is too big. I'm not against big heads on the baby animals, but the puppy's head is crazy large -- bigger than the adult dogs' heads, I think! -- and it looks really weird. --72.208.204.70 04:35, 23 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 Fixed/Skipped

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)
