Minecraft Wiki:Issues/1.2.4

Organization of This Page & Instructions
Note: 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 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.)

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 undefined. 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  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.

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 </tt> = 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>.

!! every time I start minecraft after the latest update, after logging in I always get this

Before this latest update I got nothing of the sort, and this happens every time for me, I know it is just the latest update for some reason, because I also play games that are much more intensive on the drivers than this. I would like a fix somehow. Also, feel free to move this if it's not in the right place.


 * I think the problem could be 1 of 2 things (or both) 1. LWJGL Glitch (Replace with new LWJGL jars, if you don't know how, look it up or 2. Outdated or incompatible graphics drivers (You may need to downgrade or upgrade, try upgrading first  RyanDolan123 00:34, 30 March 2012 (UTC)

undefinedSand sticks to the bottoms of blocks which are supporting minecart tracks.

Fixed/Skipped f mp After executing a command in the chat box, Minecraft will not exit the entry box thus the player is stuck in talking mode. Entering another command or text will, on a few occasions, 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.

f 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)

f 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

a Boats do not clip properly into slabs. Cactose

a Minecarts with Chest and Minecarts with Furnace are useless, since you can't link minecarts together. (This is going into suggestion territory, but if chains were added for this purpose they could also be used to craft chain armor.) If they worked well then they would be quite useful for underground mines.

a The fact that boats do not drop themselves is all the more annoying given their fragility.

a Minecarts appears to fill up with water. Cactose

a Minecarts cannot be used to build rollercoasters on most Creative worlds due to minor lag glitches stopping or even reversing the direction of carts. Most noticable when trying to build upward straight slopes to exploit the 256 building cap, doesn't 'seem' to happen under around level 90. Much worse when trying to use detector rails to power powered rails, still happens with redstone torches. The cart often stops at lv 114 and refuses to climb normal rails regardless of speed, losing all momentum at the edge between the powered rail and the standard rail.

! 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)

!cr Redstone torches in creative mode burn out after 7 to 8 uses and not re-light. If a burnt out torch is replaced with a new torch, then the new torch will burn out on the first use and stay that way. --76.227.102.45 02:49, 25 March 2012 (UTC)

 * This is a consequence of how redstone actually works when traversing a slope. Basically, the fact that glowstone is a "transparent" entity but can have redstone placed on top of it causes the redstone signal from it to only be able to propagate upwards on the slope instead of downwards. This is a highly useful property in many situations actually, although it is technically a bug. 75.64.176.235 19:16, 28 March 2012 (UTC)

 * It does the same when a block near aan open fence gate is destroyed. Dexes TTP 18:02 2012/03/23
 * Same thing happens to regular wooden doors too. This can't be easily fixed because doors/trapdoors/fence-gates are all redstone powered items. While you can toggle them manually, anything that triggers a local block update on them (destroying a block next to them) will cause them to check their redstone status and update accordingly. Thus, an open door with no redstone power will revert to a closed door when its block update is triggered. Fixing it would involve changing rather large parts of redstone behavior. 75.64.176.235 19:22, 28 March 2012 (UTC)

undefined Inverting the signal of a redstone wire by placing a redstone torch onto a block and powering the block costs 1 tick of signal duration. If the duration of the redstone signal is only 1 tick long the signal does not get through the inverter. This can be tested by building a quick pulse limiter, inverting the signal from it and observing the shorter pulse that results. In larger redstone creations which may invert the signal many times the pulse is more and more likely to entirely disappear.
 * This seems to be part of a wider "instant wire" problem. Redstone isn't like a well-defined cellular automaton, but updates step by step in no particular order. That wreaks havoc on any and all redstone timing. Torches seem particularly susceptible, as are pistons. Instant_torch.png Here's an example of mine where a torch blips even though its input is always on for most purposes, and torches don't normally react to this sort of thing (unlike trigger-happy pistons). Details are on the image page. The converse is also possible. I really wish entire circuits would update atomically like a cellular automaton, so you can be sure of what it does. It's pretty cool that you can abuse the timing, in particular with pistons, but in the end it's a pain to get the timing of very basic circuits right. --Jonathan2520

undefined If you place a sticky piston next to a powered rail and power the piston with 1-tick pulses, the powered rail will be pushed back and forth and also drop as an item, causing it to duplicate. The piston head also disappears when extended while doing this.

undefined It is possible to use a sticky piston to pull a normal rail or detector rail (but not a powered rail) up into the air. In this state, minecarts can pass over the rail, but any change that causes a block update to the floating rail will cause it to be dropped as an entity. --174.54.79.43 20:07, 26 March 2012 (UTC)

undefinedmp Sending a 1 tick pulse to a sticky piston with a block on it can create a client side block in the retracted position, while the the block in the correct position remains invisible. This is easier to reproduce when powering multiple pistons.  The wool marked by torches are in the wrong position. If a block is placed on top of them, or the client reconnects, they will be removed and appear 1 block above. Tested on a vanilla 1.2.4 server. 4338A 23:09, 27 March 2012 (UTC)

undefined Pistons pushing a player or blocks into a player can cause the player not to be affected by blocks they collide with. Pistons will push players inside of blocks potentially causing suffocation or breaking some redstone contraptions.

undefined Walking on redstone repeaters, set in a simple 4x3 circuit relay, occasionally causes the player to fall one block down and become stuck. Resolved by a jump.

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)
 * In fairess, the wiki pages -- including the redstone repeater -- are community pages, not Mojang pages. This just means that the community has not documented this yet.
 * Why don't you try editing the page and putting the information in? Since you have done the work to decipher what is happening, you are probably most qualified to update the page with the details.

a When standing on a ladder and destroying another ladder, actually we destroy the block on which the ladder is placed. Tried with cobblestone behind, did not try with other blocks. (Multiplayer, Linux 64 bits)
 * Can't duplicate in SMP on Mac -- I can break the ladders both above and below the one I'm standing on. In fact, I can't break the block behind them even when trying, because the ladders are in the way and I'm too close to their hitbox to access the block. --Rifflesby 21:13, 28 March 2012 (UTC)

a Obsidian's time should be reduced to AT LEAST 5 seconds since it is very soft IRL
 * Obsidian is the second-hardest block in the game -- only bedrock has more blast resistance, and it's the only material you need a diamond pickaxe to mine. A long mine time is perfectly appropriate. Its hardness IRL is not in the least bit relevant. --Rifflesby 22:46, 30 March 2012 (UTC)

a! Digging up gravel will sometimes yield flint. This is a major annoyance, especially when you're using gravel for decorative purposes. Players are losing resources to gain a resource they never even wanted. Since this is a crafting game, it doesn't make sense why gravel can't be just crafted into flint. This could be why some people don't use gravel as a decoration. (Trenix 01:48, 28 March 2012 (UTC))
 * This has been a feature for almost forever. Why would they change it? There is a 1 in 10 chance gravel will drop flint and if they changed it so you can just craft it with 1 gravel or something it would just be stupid at this time. If they don't want the flint they can just burn it in lava and dig up more gravel. It also depends upon what you use to break it. Using your hand will take more time but it will drop less flint, using a shovel takes less time but drops more flint.

a Decorative sandstone, a block that looks like it has hieroglyphics on it, can be crafted and is not unique. If it was unique by being only found in generated desert structures, there would be an actual reason go into deserts, rather than just looking for sand. (Trenix 17:25, 27 March 2012 (UTC))
 * Considering that there aren't any generated structures that use them, in the desert or elsewhere, the only thing that taking the recipe away would do is make them entirely unavailable. --Rifflesby 00:22, 28 March 2012 (UTC)
 * Thought it was obvious that I was asking for generated structures in deserts. I updated it to make it more clear. (Trenix 01:24, 28 March 2012 (UTC))

a Logs should last four times as long as planks since it divides into 4 of them.--MCKMan
 * Definitely agree, different wood types should also burn longer than others. (Trenix 01:19, 27 March 2012 (UTC))
 * It's for balance reasons. They aren't going to make coal useless --Moxxy 02:54, 27 March 2012 (UTC)
 * Planks burn for 15 seconds. MCKMan said that logs should burn four times longer. Now lets do some calculation, 15 multiplied by 4 equals 60. So MCKMan is asking for logs to burn for 60 seconds. Coal burns for 80 seconds. That means coal will burn 20 seconds longer than a log, thus making coal not pointless and still being useful. Besides, crafting a log into a plank is not difficult. The problem is, using a log as a fuel source is a bad investment. (Trenix 06:27, 27 March 2012 (UTC))
 * That's only 33% efficiency for a resource that's much harder to obtain. It indeed makes it useless to mine coal when trees are renewable. --Moxxy 20:15, 27 March 2012 (UTC)
 * Coal is easy to obtain and is commonly found underground just about everywhere in large quantities. Coal also has unique uses, other than being used for fuel, like making torches and fire charges, which wood can not. While coal may not be renewable, charcoal is. Charcoal is the exact same thing as coal, with the only difference is the name. Therefore I still disagree, coal would not become useless. (Trenix 20:54, 27 March 2012 (UTC))

a You are unable to place a chest next to a large chest. I'm assuming this is because large chests are created when chests are placed next to each other. A way to resolve this issue is having us craft large chests inside our crafting table or inventory, rather than having them be created by placing them down. You are also unable to place small chests next to each other without having them be combined. (Trenix 17:42, 27 March 2012 (UTC))
 * Downgraded to annoyance. --Moxxy 19:50, 27 March 2012 (UTC)
 * Yes, this is pretty annoying. I think I would like it better if we were able to just put down the chests like it is now, only have it so that you can place large chests next to other large chests. This shouldn't be too hard to do actually, if you make it so that a large chest will not try to reconnect to another chest beside it since it's already connected to one. Don't know if that made any sense... I am generally terrible with words.--SeanRamey 17:16, 28 March 2012 (UTC)
 * I've wished for that myself. It might be a bigger deal than it sounds, though -- I suspect that the big chests aren't actually a discrete entity, it's just two chests that are faking, and know to do so because they're next to each other. If a chest could be adjacent to two other chests, it wouldn't know which one it was supposed to share with. And the data bits can't be used to store that, because they're already being used for the direction the chest is facing. The notion of crafting two chests into a large chest might be a possibility -- the bed is also a two-block placeable -- but I doubt the team would much feel like wrangling that code when there are much shinier things to work on. --Rifflesby 21:32, 28 March 2012 (UTC)

a! Recipes are needed for Circle Stone Bricks and seamless smooth Stone Slabs.
 * To clarify about the seamless smooth Stone Slabs: There is an unused type of slab and double slab with damage value 6 that uses the top texture of stone slabs on all sides. Even though it looks cool, it is unavailable. It should either be made available or be replaced with something else.

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.) --Rifflesby 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. --Rifflesby 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. --Rifflesby 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.
 * I'd also like to see sandstone stairs, smooth stone stairs, grass and dirt slabs and stairs, gravel and sand slabs (not stairs), clay slabs and stairs (from 2 or 3 clay balls), glass slabs and stairs. Knowing what it takes to work glass in a kiln in real life, maybe glass stairs and slabs would require a better furnace, or a "hot workbench"? Maybe a "Hot Workbench" would be needed for some other technology items ... steel :-). Keybounce 00:07, 27 March 2012 (UTC)

a Placing one block frequently places two when having only clicked once.

 * I've had this happen a LOT on a slower computer. Getting Optifine reduced the issue, but did not solve it.
 * Specifically: Optifine has two options, one for input adjustment, and one for output FPS smoothing. I had to turn both on (one is off by default). The issue is that the game only checks for keyboard activity between frames if the GPU is idle; by default an OpenGL driver can render every third frame and be compliant. This means the game is spending 2/3rds of its time ignoring you. It then timestamps the incoming key/mouse activity, and considers that three frames of time have passed, and concludes that's enough for two placements.

 * Another words, I want giant mushrooms to be only created in mushroom biomes.
 * I can't get behind that at all. They're too cool to be only available in such a rare environment. Now, if they could only be produced on a mycelium block (which you would have to take Silk Touch to a mushroom biome to get), I would be okay with that. --Rifflesby 00:28, 28 March 2012 (UTC)

 * What about worktables and furnaces. They stack. Everything else should too. Maybe in smaller stacks but when going on long mining expeditions or doing a lot of terraforming, it would be damn handy to have your tools stack. -- Lucifer_LLS 11:28, 28 March 2012 (UTC)

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.

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
 * Agreed.--SeanRamey 17:24, 28 March 2012 (UTC)

a! The other serious glaring problem with enchanting is having to click-click-click to get the number you want. This is a system that hasn't been used by serious game developers since the old days of RPGs that let you roll your own stats; the intention of allowing the player to re-roll a random outcome is noble, but the result in reality is that, knowing a better outcome to be available, the player will simply mash the button, becoming increasingly frustrated, until their number comes up. It needs to be replaced with a slider or text-entry field so the player can simply say how many levels they want to spend. --Rifflesby 00:35, 28 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)

undefinedsu If you carry an empty bucket with you when diving, you can stay underwater indefinitely without drowning by collecting the water block just in front of you and the emptying the bucket on a nearby solid block each time your air meter gets low. The brief pocket of air that forms refills your meter. It's something you can choose to use or not, but it negates the need for the diving related enchantments and generally lessens the survival aspect. The code already checks for surrounding water/solid block for the purpose of filling the taken block with water, could it be modified to prevent the brief air block? --LoneCenturion 20:51, 31 March 2012 (UTC)

 * Seriously? Come on man, this page is for specific issues, so the devs can look down the list, fix a thing, and then check it off. "This game is not sufficiently like Wasteland" is basically the opposite of that. What are Jeb and Dinnerbone supposed to do with that comment?

a Snow isn't formed under signs, fences, fence gates, saplings, flowers, mushrooms, cobwebs, and doors. This gives them an unappealing look when in a snowy biome. (Trenix 01:38, 27 March 2012 (UTC))
 * Two blocks can't occupy same space. That's like water and ladders, slabs, doors... — MiiNiPaaT
 * Snow is the same as farmland. However, farmland can have crops on it and snow can't have anything on it. I'm pretty sure it can be possible. Make it so you'd have to break the block on top of it to clear out the snow under it. (Trenix 17:30, 27 March 2012 (UTC))
 * Snow layer is a block, it is not a modyfier on blocks or anything. Snow — this article states this, this is an example of toying with snow metadata. It's like a Lily pad in terms of thickness, but does not have a hitbox. Farmland on other hand is block which replaces grass/dirt block an if it wasn't non completly opaque block you could hav snow covering farmland. — MiiNiPaaT
 * Maybe snow shouldn't be a block. (Trenix 19:21, 27 March 2012 (UTC))
 * The way blocks are coded there are not enough bits for this to happen (See Jebs tweet on different half-slabs in the same spot). Since this is completely impossible can we remove it please? --Moxxy 20:37, 27 March 2012 (UTC)
 * We thought pressure plates couldn't probably be used with double doors, guess we were wrong. I'm sure Jeb could think of something to fix this too. Nothing is impossible when it comes to programming, you just gotta find a way to make it work. So no removal until we get some official word from mojang. (Trenix 21:04, 27 March 2012 (UTC))

 * Actually, it's also possible to create a snow entity, which could be in the same position as blocks like fences. It would not replace snow cover on top of blocks, and would have no hitbox, and the removal of the block it coincides with would turn it into normal snow cover. All of this isn't too far-fetched, as paintings and Ender Crystals are both entities (and the latter does superimpose with a block), and although this would surely have implementation issues, it's not in the slightest "impossible". ~WolfieMario

a mp "User A and B are in different dimensions. No tp." - Could it be fixed please ?
 * I'm fairly certain this is intended behavior.

a in SMP, you can't use enderpearls to pearljump in gamemode 1.
 * This is intentional.
 * It's meant to be that way.
 * Why - it makes no sense? What is the advantage of them not working?
 * Perhaps to persuade to to reach the end in survival? Creative is mainly for building.--Shikamaru123 06:47, 24 March 2012 (UTC)
 * That's eye of ender. I was talking about enderpearls. And besides, creative mode is about being unlimited; having a limitation of not throwing enderpearls makes no sense.

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

a You can't ignite TNT by leftclicking on it with flint and steel while in gamemode 1.
 * 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.
 * Moxxy has been deleting this bug report, without leaving an edit summary explaining himself. I am quite mystified as to why he is doing that - it is clearly an error that the "flint-and-steel ignites TNT" feature is not working in Creative.
 * In creative blocks are instantmined causing flint and steel's effect to be skipped.
 * Which is obviously a bug that they are instantmined instead of ignited.
 * Why? I've never played much Creative, but it's my understanding that everything is instamined with a left-click, yeah? Why would you expect TNT to be different? The exception would be strange. I also don't understand why this is an issue to begin with -- is there some reason you need to be able to left-click to light TNT instead of right-clicking? Thinking about it, it seems to me like if there's a bug here, it's that you can ignite TNT in Survival by breaking the block with your lighter instead of actually using the tool properly to set it on fire. --Rifflesby 09:43, 30 March 2012 (UTC)

TNT instamined in Sirvival too. Main problem with rightclicking is that there is no posiibility to innite one and only on from several TNTs in group. Also there is a non-predictable delay between clicking and actually igniting. — MiiNiPaaT
 * Surely if you need that degree of precision, you should be using redstone, no? From looking at the 1.2.5 changelog, it seems that the team had the same thought. --Rifflesby 23:29, 30 March 2012 (UTC)

a!mp Will occasionally experience major game lags while in the Neither.
 * Can confirm that, I feel it may be the new sounds of the lava, but I am not sure. Hope it can be fixed. The nether which is so vital is almost unbearable now. ~DaleK 16:57, 24 March 2012 (UTC)
 * I can also confirm this, and a friend of mine can also confirm this. I saw in the 1.2.3 section, the exact same bug, but he believed it to be the lighting system. I have also noticed that the RAM usage of Minecraft in the nether goes from about 300mb, gradually increases to about 1.5Gb then dumps it all back to 300mb and repeats. I have allocated 4Gb to my Minecraft. I have a AMD phenom II x4 3.4ghz, a Nvidia GeForce GTX 460, and 16Gb of RAM with windows 7 64bit. This shouldn't be producing major lag spikes.SeanRamey 04:25, 27 March 2012 (UTC)

a!Problem: When in Single player mode (Maybe multiplayer, didn't test) if you make a nether portal above the old height limit, enter the nether, and return, a new portal will spawn on ground level. Idk why. Probably a problem with the anvil thingie...
 * tested and confirmed. In fact the problem is much more severe. Creating a neither portal anywhere will bring you back to the first one you make. Plus if the first portal made is above old height limit, it will bring you back to a new portal, as mentioned. Tested in creative SMP. Upgrading to major annoyance.

a This problem had been around for a while. Eating from a stack of more than one food will often result in consuming 2 of the food instead of intended 1.

a On some servers, random Fire Charges float and blink in the sky.

a! Golem recipes are not idiot-proof, they do not discriminate whether the required snow or iron block formation is standalone or part of a structure made of snow or iron blocks. The recipe should require air blocks to exist around the snow or iron blocks to ensure that Golems are not created accidentally.

a! Leather is useless because it is only used for creating inferior armor, and since animals don't just respawn on their own anymore, it is far easier to just find iron for iron armor than to start the cow farm required for a reliable source of leather.
 * Leather blocks/slabs/stairs would be fun for making furniture out of, though there's more important and glaring holes in the recipe list that I'd want to see filled first. It's true though that leather armor doesn't get much use, outside of challenge maps ("Super Hostile" for instance). Perhaps some leather-only enchantments? Boots of Speed, etc... --Rifflesby 03:04, 26 March 2012 (UTC)
 * The only way you can fix this is to increase the movement speed of a player who is without armor, then having iron, gold, and diamond armor slow you down. That way, having iron, gold, and diamond armor will make you move at the same speed as you do now, but wearing leather will make you move faster without making it act as if it were enchanted. Another way to improve this is to give leather more recipes. For example, the book recipe could have leather added into it, since leather was used as a cover for books. (Trenix 01:55, 27 March 2012 (UTC))

a! It is very annoying that you can't make portals that are 3 blocks wide, it can make you have to give the entire place a makeover just so the portal can fit symmetrically.

a! It is frustrating that there is no storage block for the most common and inventory-clogging ores, redstone and coal, yet there is one for the rarest ore, diamond.

a! Once you already have a good wheat farm, you don't need to keep wheat seeds because the seeds that the grown wheat drops will be enough for replanting your farm, and you will have too many useless seeds left over after. They are annoying to dispose of and they would at least be useful if they could be used as (inefficient) fuel in a furnace.
 * If seeds were used for breeding animals while wheat is used for getting them to follow you (or vice-versa), that would give extra seeds a purpose as well as solving the problems people have where unbreedable animals get in their way while they try to feed the others. --Rifflesby 00:50, 28 March 2012 (UTC)

a Axes are not good for breaking leaves, so there's nothing that can break them quickly without taking extra durability damage.
 * You don't mine leaves with axes, you do it with shears.
 * I imagine the OP is talking about breaking them (to get saplings/apples), not collecting them as inventory objects as shears do. --Rifflesby 03:16, 26 March 2012 (UTC)
 * Yeah, that's what I meant. It would make sense for axes to be good for bringing down all the parts of a tree. This is possible, rails already do this where pick is best and sword is better than nothing.
 * You have to remember that leaves are attached to a branch. Picking away leaves from a branch or picking away the branch itself is not very productive. Branches are more thinner and flexible than logs and leaves are extremely small. This is why shears are used, they can easily clip these objects. Otherwise you'd see landscapers outside with hatchets. (Trenix 02:16, 27 March 2012 (UTC))

a You can sleep in a bed surrounded by tall grass (possibly other similiar blocks too) but you can't respawn in it. --Trinistr 09:14, 26 March 2012 (UTC)

a You cannot generate a Nether Portal block (with a Nether Portal) next to another Nether Portal block (with another Nether Portal) in such a way that they have no space between them, and the two Nether Portals do not share any obsidian.
 * That is pretty confusing. I don't have any idea what you are trying to say. Maybe you should rewrite it.SeanRamey 04:38, 27 March 2012 (UTC)
 * I think the OP is trying to make two adjacent portals face-to-face, creating a 2x2 column of portal blocks. -- Orthotope 06:47, 27 March 2012 (UTC)

NPC/Animals
Bugs

undefined If you push a cat off a chest or bed while its sitting, it will stand up. Because the cat is no longer sitting, it will then teleport to its owner if the owner is not present. Technically a non-owner can make a pet stand up, which is very problematic in multiplayer. I'm pretty sure an owner wouldn't want their cat to teleport to them when they're around lava in a cave. (Trenix 21:35, 27 March 2012 (UTC))

undefinednpc's don't close doors that the player opened anymore. they did that in the beginning. this is a large bug because zombies can walk right in. when they entered a house at night and I opened the door, they would close it for me but that doesn't happen anymore. please fix jon!:)

undefined cat's seem to have difficulty to get on top of chests. when my cat runs towards a chest, he just keeps jumping against the side

? 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

! Nearby (100-200 blocks) 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.


 * Confirm: seen by myself and a friend on two different servers running vanilla 1.2.4. Worlds are converted, cats and dogs where present and already tamed before conversion. Doesn't happen all the time: after upgrade, I've played a few hours without problems, all pets where sitting at home. Then suddenly all of them appeared at once while I was building a skyrail a few 100 blocks away from home. Maybe I crossed that distance for the first time since upgrade, but I'm not completely sure. They immediately started to push one another of the rail, causing all dogs to die from fall damage. Cats survived the fall and reapeared again and again, pushing me around, I barely escaped the same fate. I consider this a major bug, because uncontrollable tamed cats and dogs can easily cause the player to die, you either have to stop playing/building in dangerous areas, or you have to kill all your pet animals.


 * Untamed wolves and ocelots follow me and teleport.

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? --Rifflesby 08:27, 23 March 2012 (UTC)

undefined Chickens look down at the ground instead of up at you. --Rifflesby 22:07, 25 March 2012 (UTC)

 * Nevermind, I can confirm that, when getting a chicken to follow you with wheat, its vertical positioning of its head is inverted. When you are standing on higher ground, the chicken looks down. When you are on lower ground, it looks up.--Mattrition 16:42, 31 March 2012 (UTC)

undefined Livestock animals escape fenced areas (even two fences high): notably chickens, and cows, will find their way out of a fenced area, even when it's two fences high. Chickens stand right up against doors, and the actual fences staring out to the other side as if conjuring a way to escape. Leave the area and come back, and a bunch have escaped. Cows still seem to push one another up and over fences. (Nattydred 03:06, 29 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. --Rifflesby 04:35, 23 March 2012 (UTC)
 * Solution! Put your chest where your cat can't reach it.
 * It would be cool if cats only did that when they were low hp. I'm thinking this is a bug since they seriously get stuck on these objects until they're broken. New features are supposed to be strategic and fun, not annoying. Hiding your cat from beds and chests is not strategic, it's just frustrating and pointless. (Trenix 02:38, 27 March 2012 (UTC))

Suggestion: if you can stand on your chest, you can push the cat off and when it stands, quickly click it to make it sit before it jumps back on the chest. Failing that, holding fish in your hand will get a cat's attention and it will crouch and slowly walk towards you and off the chest. It's a bit tricky to get it far enough away that it won't run back to the same chest or another one in the area.(Nattydred 03:06, 29 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. --Rifflesby 04:35, 23 March 2012 (UTC)
 * Yeah, it's bigger than its body! When you look at it from the front all you can see is the head.

A Villagers seem to be reproducing way too much, I have a home in a village and it is packed with children. 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. --Rifflesby 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)
 * Typical for cats, that they won't do what you want them to do.. ;) --Locoloco 10:42, 24 March 2012 (UTC)

a Groups of redstone lamps that are hooked up to a circuit that makes them flash are very glitchy when viewed from a distance. they don't appear to all go on or off at the same time, even though they are all hooked up to the same power source. this happens on both survival and creative and does not go away when smooth lighting is on.

a! Iron Golems freezing up and becoming immobile if they get pushed into water makes a certain sort of sense narratively, but if your village borders on a river it becomes an incredible aggravation. Bustling villagers are constantly knocking them into the river, making them useless, and you can't even push them back out -- you have to kill them so they respawn. It's just a hassle. Please give golems the sense to climb out of water under their own power. Perhaps you can reuse the skeleton hiding from light code or something. --Rifflesby 08:52, 25 March 2012 (UTC)
 * Agree with this annoyance. However, temporarily removing the water works to get the golem out (rather than killing it).

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)

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.

 * This occurs on my server, but I've seen it from 6-7 blocks phased through lateraly and as many block as are present verticaly

undefined mp Possibly related to the above bug is that Mobs still tend to have "placement issues" in SMP and still tend to get stuck inside blocks. Even more noticeable is the way that animals get stuck in the ground foliage of jungle biomes and, if killed when stuck in a leaf block, leave loot behind that can't be picked up unless you destroy another block beneath that. --Mattrition 10:00, 25 March 2012 (UTC)

x mp su When placing an upside down slab next to an upside down stair makes light level 0 on them.

! Switching to fullscreen can change the operating system's gamma value. On my system, I always have to choose the lowest gamma Windows offers, and Minecraft resets the value to default when I switch to fullscreen. As soon as this happens, the lightness slider has no effect on in-game brightness. I'm running Windows 8 Consumer Preview 64-Bit, Java 7 64-Bit, NVIDIA GeForce GTX 560. The issue has not always occured, but since yesterday it occurs persistently, both on MCPatched and Vanilla Minecraft, regardless of Brightness value and Advanced OpenGL on/off. I suspect this is some weird combination of LWJGL and Windows 8 issues, so next I'm going to try and update LWJGL. --GALAKTOSTalk – Win8βx64, Java7x64, NVIDIA GeForce GTX 560 09:33, 29 March 2012 (UTC)

The original submission was: "On a converted map, all torches that were previously placed or are currently placed in a 1 block large space above you creates a "dark" space. http://i.imgur.com/z1URb.png If you chip away at the adjacent block, this "dark effect" goes away.

 * In my SMP world we have a central area lit with inset torches in the ceiling, and it never had the bug until 1.2.

undefined sp su When updating older maps such as Vechs' Super hostile maps (http://www.minecraftforum.net/topic/191908-ctmcollection-vechs-super-hostile-series/) to anvil, the lighting will be consistent throughout the map. This makes unlit caves just as bright inside as it is outside, depending on the time of day.

undefined Anvil only stores 16x16x16 sections that have blocks in them. On load, Minecraft assumes skipped sections have full sky light and no block light. Even if it there should be a shadow cast by sections above or block light coming in from neighboring sections. I should add that this primarily affects blocks right next to a skipped section. It's still quirky no matter what, but I haven't touched Minecraft enough lately to write an accurate report on that. --Jonathan2520

a! sp Not sure if its a map thing but when i try to play any map pre anvil it makes all light as if it were exposed to the sunlight and it changes with the sun. so all skeletons and zombies burn as well as spiders going docile

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)

Bugs undefined 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).

 * No, even at ground level. Also I decided to upgrade this to a minor bug because even though it is not major and is just annoying, it is still a bug. For things like this, the regular minor bug tag is good enough.

(Linux 64 bits)

a In the multiplayer server list, descriptions of servers often overlap the player/slot count on the right of the interface. In 1.0, this issue also existed. In 1.1 - 1.2 the player/slot count was much better positioned: more to the right of the interface allowing for less overlap. In 1.2.4 the player/slot count has again returned to the center-right of the screen forcing many server descriptions to overlap the players/slots count. - d3fin3d
