 * Marked as minor bug as any crash is beyond "annoyance" IMHO. It might be a major bug if the crash is related to world loading. I also fixed the headers for this section, they were in the wrong order -- Featherwinglove 10:29, 27 July 2012 (UTC)
 * I think this is a bug that occasionally appears during world generation. And if this crashes a game, shouldn't it be marked as critical? --Acomputerdog 14:22, 27 July 2012 (UTC)

Gameplay
Bugs ! After his death his spawn point changes, precluding the gameplay of some custom maps, and compass does not point to their spawn point. NOTE: also the definition Without the bed, the bed works, the problem is with the natural spawning
 * Confirmed, I've seen this occur with certain maps. --Nathan2055 16:04, 28 July 2012 (UTC)
 * (Duplicate merged 16:04, 28 July 2012 (UTC)) With Single/Multi-Player Mode Merged, Spawning now works like it does in Multi-Player for Single Player maps. This breaks the Spawn points in my maps, and it will break the spawn points in any other user made map, unless they set the player spawn with a bed (not always possible - depending on the map type) or start the player in a 20x20 room. It would be nice to have a way to control the spawn point, maybe in creative, for map makers. --Brandonn

! Lingering in a Dungeon with an active Spawner (i.e. unlit by torches) the arrows of false-spawned Skeletons are fired at, and inflict damage on, the player. Video Zingrook 20:00, 27 July 2012 (UTC)
 * 404 on "false-spawned", can you please explain or provide a link to an explanation? -- Featherwinglove 10:32, 27 July 2012 (UTC)
 * Happened to me yesterday while playing with slightly earlier snapshots (Both 12w30c and 12w30e I can confirm this with.) All instances were SSP on Peaceful. The spawner fires an arrow roughly from the same height as spawner it's self, rather than where a skeleton would normally be firing. (it appeared that way anyway.) No skeleton model appeared in any of these instances, though the spawner did spin faster, and generate fire particles as if it were attempting to spawn one. The arrows seem to be fired during the tick where the skeleton would normally spawn. Arrow could not be collected after firing. (For me atleast.) --184.52.125.240 12:50, 27 July 2012 (UTC)
 * Odd. First of all, skeleton arrows can't be picked up. Secondly, this is most likely a bug that involves the skeleton firing in the same tick that the game despawns him in, resulting in no model appearing. However, I don't think this is major. Consensus to downgrade? --Nathan2055 16:04, 28 July 2012 (UTC)
 * Since we just had the "nerfing" of TNT in peaceful mode, the chance, however small, that a player could actually take damage from something that they didn't intend, should merit this a bit more attention. Conversely it is a minor annoyance and could stand to stay in a for a few more versions, so long as it's a notable issue in those versions' bug lists. --184.52.125.240 22:33, 28 July 2012 (UTC)

! Traveling to and from the Nether is still frequently failing to render the world, resulting in either the player falling out of the world to their death or getting stuck in the unrendered terrain. 69.113.144.41 14:30, 26 July 2012 (UTC)
 * This is a major bug that is resulting in many players losing good gear, so I moved it to the top.
 * Tested this on a SMP server, seems to be a chunk loading error...doesnt always happen though. Happens more often when you leave the nether and enter the nether rapidly. --Hazado22 17:59, 26 July 2012 (UTC)
 * I had this happen to me. /tp'd out of the area into the main area (I had managed to get stuck at y=20 and not fall farther), and found LOTS of unloaded chunks. A long row of them about 5 or 6 chunks from the portal, and a couple at the portal. --Keybounce 04:25, 28 July 2012 (UTC)
 * I have also experienced this. It never happened in 12w27a, and occured sometime between then and 1.3 preview. 05:16, 28 July 2012 (UTC)
 * Also happens to me, multiplayer and singleplayer. Roughly 50% of the time, immediately post-warp, the local chunks will take too long to load, causing me to fall through the world. 76.121.2.134 00:46, 29 July 2012 (UTC)
 * I have tried to reproduce this bug in MP, and in my case it almost ALWAYS happens when I visit the Nether second time after login, that is, when chunks near portal have already been sent to client during current session. Exception is when you re-enter Nether immediately after leaving it (Looks like chunks are still not unloaded). Possible workaround is to always reconnect before entering Nether (it worked always).--213.87.131.173 16:07, 29 July 2012 (UTC)

! Every now and then, for reasons unknown, lever, pressure plate, tripwire, redstone, water, and lava fail to update for the remainder of the current session. If you reload the world without fully restarting Minecraft, the application will crash. --lance6422 20:25, July 26, 2012 (EST)
 * Can you get a crash report? --Acomputerdog 13:11, 27 July 2012 (UTC)
 * This should be upgraded to critical if a crash report can be obtained. If it exits showing a Minecarft logo and a crash report, check in .minecraft\crash-reports for the latest file. If it just closes, check in the root of .minecraft for a .log file with the text "hs_err_pid" in the name. --Nathan2055 16:04, 28 July 2012 (UTC)

!mpcr Traveling in the nether, just two people, nothing fancy: repeatedly the server would stop responding to the clients, and the clients disconnected.

! The builtin "speedhack" detection breaks elevators and other legitimate piston contraptions that transport a player "too fast". It manifests itself as getting stuck in the device due to the movement, caused by the piston pushing the player, being denied by the server. This used to be an issue on MP only, but now that the client is effectively a server as well, it affects SP too. --NTT 13:42, 27 July 2012 (UTC)

undefinedmp Signs sometimes go blank on multiplayer. I think this also happens when the sign goes out of your visual boundaries. --NeonJ 18:45, 26 July 2012 (GMT)
 * I have encountered this problem in several of the prerelease versions, but it fixes its self every now and then. Not sure of the exact cause. --Osiris08 of mcworldmap.com
 * This has been happening to me pretty often. Random signs are blank, sometimes all in an area.  They're never blank when loading into a world with signs in the initial chunks, but once the chunk(s) are unloaded and reloaded the signs may be blank.  Seems problem could be related to render distance, as I use Normal distance/32-bit Java; others with Far distance don't seem to have the problem (or at least as often).Jovet 09:08, 28 July 2012 (UTC)
 * (Merged duplicate) Text on signs only show up in the chunk you spawn in. Once you leave that chunk, there will be no text displayed on signs --Porrohman
 * Sure that you're playing 1.3pre ? That specific bug was fixed with 12w30a --Kumasasa 09:02, 28 July 2012 (UTC)

undefined Exiting boats cause them to break when next to a wall. Logging off ejects you from the boat. (Bug report added with tampered signature, submitter unknown)
 * Smells like your Minecraft server exceeded your physical memory and started using virtual memory. Make sure the computer it is on has at least 1GB for the server (2GB total memory), and if the system meets that, you can adjust the server's memory allocation with the instructions here. Also try the same thing with 1.2.5 and see if the behaviour changes. -- Featherwinglove 10:42, 27 July 2012 (UTC)
 * I'm sorry, someone altered my bug report. This report was not mine, but the tail end ("Multiplayer, ... " through to signature), was mine. My report was about the nether far UP the page. I do not know who reported the boat issue here. Keybounce 19:20, 27 July 2012 (UTC)

undefinedmpcr Not sure what this would be considered, (glitch?); but when I click rapidly on an item (Creative mode in Multi-player) it will sometimes duplicate or disappear completely. What i did was I kept left clicking rapidly and repeatedly on an item (not moving the cursor) and it sometimes leaves a (usable?) dupe or will have 2 of the item then they quickly vanish.
 * This can be easily reproduced if you take a stack of 64 items and button-mash the right click putting them into your inventory, you will end up with less than 64 items (haven't tried in survival mode, only creative). --24.13.232.201 05:57, 28 July 2012 (UTC)

undefinedmp When travelling on Minecarts on multiplayer, your character may take damage. This may be because of the time it takes to update the information of position of the player, what makes the server think the player falled down the ground and is "suffocating". --ViniciusBR11 20:22, 27 July 2012 (UTC)

undefinedmp I was playing on the latest prerelease connected via localhost to my own server. I was breaking a fence block with an iron axe when, all of a sudden, my axe moved in slow motion. It happened right as the fence block broke, so the particles that came off of it moved in slow motion as well. I looked around, and everything went back to normal. In the split second between me breaking the fence and it stopping the slow-time thing, I looked around and it was as if I had pressed F8 with my mouse sensitivity turned very far down. Also, right after this happened I checked the server log and it said "[WARNING] Time moved backwards! Did the system time change?" teke0884 3:07 28 July 2012
 * This seems to be a new tickrate timing mechanism, as it also happens when the server is on overload. Maybe a protection feature? --Steve G. Wood 18:56, 28 July 2012 (UTC)

undefined? Redstone circuits seem to be more reliable over short distances than before though the traveling length has been shortened to almost half of what it used to be, in certain circuits and track systems this had caused an inconvenience because they now fail to work. Circuits stop at a repeater level, the chunk for the region has also been loaded as tall towers are visible but redstone seems to not reach anymore. --- Chris 16:41, 28 July 2012 (UTC)
 * I have no idea what you mean. Redstone distances weren't altered in 1.3. Downgrading to unreproducible until further evidence is shown. --Nathan2055 16:04, 28 July 2012 (UTC)

undefinedmp i find it very very difficult to log on and when i finally do it always disconnects me from the server, this is in multiplayer and there are (correction: NO) mods or plugins installed on the server, i have a windows, with a 64 bit graphics card, and my computer is somewhat new, OS is windows vista. -- alexzang,
 * At first make sure that the server is running also 1.3pre, secondly blame the authors of the mods and plugins for that problems. --Kumasasa 07:57, 28 July 2012 (UTC)
 * Not an issue with Minecraft. --Nathan2055 16:04, 28 July 2012 (UTC)
 * Allow me to correct something here: There are _NO_ mods or plugins installed. This was last night on my server. This is stock 1.3 prerelease. About the only thing I can think of is that we (three of us) -- the two other players were in an extreme hills a good distance from spawn (about 200 blocks or so). However, even teleporting Alex to the site of the hills where the rest of us were did not change anything. Upgrading back to bug. --Keybounce 19:05, 28 July 2012 (UTC)

a! Villager trading is still very much imbalanced. Non-farmables are undervalued, e.g. 4-5 diamond must be sold for a single emerald. Meanwhile, farmable items are overvalued, e.g. 19-29 paper for an emerald. With a sufficiently large sugarcane farm, I have been able to earn around 7.44 stacks of emerald in an hour, and while this is not in and of itself bad, these emeralds can be spent of many diamond items. The net result is a far bigger earning from farming than the most efficient mining practices, even with Fortune III. In fact, just one harvesting of the farm nets a player several doublechests of diamond items, which is very overpowered. In addition, many prices are nonsensical, e.g. iron and gold are considered equal in value, and mundane items such as compasses are considered more valuable than diamond tools.

A proposed fix would be to make prices based on their cost in raw materials, and rank the materials roughly in line with their actual rarity. Farmables should have a very low value compared to non-renewable items such as mineables, because the current system leaves major exploitability from farms. Farmable offers should not be removed, of course, as it does still take time and effort to build farms, harvest them, and make the trades. One can consider comparing the amount of time it takes to farm a given amount of an item to the amount of time it takes to come across a given amount of another item when mining.

Server administrators are considering disabling trading and villagers on their servers because of the current imbalance, so this is a major annoyance. --WolfieMario 16:49, 28 July 2012 (UTC)
 * Someone also made a detailed report on an older snapshot on how villager trading is not renewable too. It needs major attention. --Steve G. Wood 18:56, 28 July 2012 (UTC)

 * There are others. Basically, fixed prices that do not respond to what's happening / supply / demand will "never" be the right price. These are, as I said in a now locked thread, worthless. Remember, people have found that the best way to deal with NPC villagers right now is to kill NPC's that don't have wanted trade offers just to keep getting new ones. --Keybounce 19:05, 28 July 2012 (UTC)

acr Flying through Vines or Cobweb in Creative Mode is slowing down the player. --Swekob 10:47, 27 July, 2012 (Swedish time)

a The new F3 altitude indicator is a little confusing, implying that the altitude is in the US standard unit "feet" more than its intention of indicating the position of the player's feet. My own nomenclature is "standing on", probably resulting in "y-so: 82.000, y-eye: 83.620" to be consistent with the debug screen's existing personality. -- Featherwinglove 00:46, 27 July 2012 (UTC)

So, for safety, one should be placed on the nearest open block at the level of the track.  If one cannot be found, then they should be standing inside the cart. 74.171.217.73 15:40, 28 July 2012 (UTC)

Fixed/Skipped

Blocks
Bugs !I reported a bug that causes the player to place two blocks in one frame in the report page for the 12w27a snapshot. Further along, I discovered that this also messes with doors, levers, and gates, where two inputs cause two state changes and thus a return to the state you are trying to frob the device from. Now that I'm playing with Pre-release 1.3, I've now discovered that this bug can also place blocks in the space the player character is occupying, probably related to the fix countering the pillaring problem associated with merge lag. Shortly before this video begins, I was trapped on the edge of the roof I was building and had to fall from it to escape. If such a thing happens while bridging in the Nether, it could be fatal. I have not yet tested for suffocation damage, but I'm expecting to find that as well. I therefore think the problem of the pillaring fix combined with the old double-input bug forms a major problem in Minecraft 1.3. Featherwinglove 00:33, 27 July 2012 (UTC)
 * Yet today i covered the top of a hole going down to bedrock (and that's a lot of blocks to update light on, so i got a huge lag spike) and when it resumed i had placed blocks all the way to my face. --Steve G. Wood 04:07, 27 July 2012 (UTC)

 * Intended and I don't see why this has to go. -- Mustek 10:25, 27 July 2012 (UTC)
 * Agreed. Dinnerbone (I think) has stated that one difference between tripwire and pressureplates is that tripwires can float. I would be disappointed if they took this away, as it's one of the biggest points to using them, and I have plenty of contraptions that rely on floating tripwire. --WolfieMario 12:03, 27 July 2012 (UTC)
 * I would like this mechanic to stay aswell, but with one modification: Rather than having to "stack" string on top of it's self to make lines, it would be far easier, and all around smarter to allow "stringing" directly horizontally from the tripwire hook it's self. This would allow quicker builds, as well as cleaner setup in general, plus it would allow you to build tripwire receivers across ravines. Why you would need to I have no idea, but I am sure there is a use, possibly involving TNT Cannons/Mob Launchers, some sort of "accuracy challenge." --184.52.125.240 13:24, 27 July 2012 (UTC)
 * Yes, it would make more sense to string directly onto a hook, and I'd really like that. Of course, string should still also be placeable against other string, to make stringing across gaps actually possible. I suppose placing string vertically on other strings isn't necessary, but I don't see any problem with leaving that in as well. --WolfieMario 14:35, 27 July 2012 (UTC)

a Mushroom blocks can't be harvested or placed properly, reverting to damage/data value 0, a block which appears to use the mushroom pore texture on all six sides. This makes it impossible to use the red, brown, and white mushroom block textures in creations without using pistons to push blocks around. It is also inconsistent with the expected behavior of silk touch: if silk touch is capable of harvesting a block, it should not transform it upon harvesting. Transforming a block upon its placement (which happens when placing mushroom blocks of any damage value, obtained through cheats available in vanilla) is also completely illogical and a roadblock to making things from the mushroom blocks. Perhaps mushroom blocks could be made properly harvestable as "Red/Brown Mushroom Top", "Red/Brown Mushroom Edge", "Red/Brown Mushroom Corner", and "Red/Brown Mushroom Stem", where the edge and corner blocks would be placed in a directional manner similar to pumpkins (upside-down mushroom blocks would not be available, as this would require splitting the current two mushroom block data values into multiple). --WolfieMario 13:44, 12 July 2012 (UTC)
 * I like fix you suggested. Totally support. 93.106.164.34 13:38, 18 July 2012 (UTC)

a Max height bug: Solid blocks can be placed until "max height -1", several other blocks can be placed on top, so the "max height": flowers, tall grass, sugar cane, torches. This itself might be a bug, it might not be, no idea. But there is an error message if you manage to place a sugar cane block on 256 and THEN try to place any block on TOP of that. You receive the "Height limit for building is 256" message (in my case). Why does this message not occur if I try to place a solid block inside 256 (which might actually be possible as it is the max height)? 80.130.166.91 16:53, 28 July 2012 (UTC)

Annoyances a! Spiders suffocate when spawned from a dispenser.
 * From a dispenser? What? 78.105.153.179 17:05, 27 July 2012 (UTC)
 * I think he means that when you use a dispenser to spawn the original spiders (NOT tested with cave spiders) from their spawn egg, that the spider created, even against the side of a glass block, will take damage (suffocate, as the OP put it) when they are created with their model partly inside the glass block. This is due to their model exceeding a one block size, and the spawn egg placement code not accounting for the spider's size when placing it. This is really annoying since it's very hard to make test builds of mob systems using spider spawn eggs in Creative mode, or to use spiders in dispenser setups when making custom maps for this reason.BrickVoid 21:17, 27 July 2012 (UTC)
 * Brickvoid is right, I mean they suffocate in the dispenser block and it does not affect cave spiders because they are smaller.
 * This, and other problems happen because dispensers are solid. If dispensers weren't solid some other problems wouldn't exist too. --Steve G. Wood 19:35, 28 July 2012 (UTC)

 * I am seeing a similar glitch with slabs put on the bottom of the ceiling blocks above. If the entire rectangular ceiling area is filled-in with upside-down slabs, all of the upside-downs slabs will be completely dark.  The wall blocks are fine.  Removing some slabs reduces the blackness. The bottom surface with spotty slabs is rendered mostly normal though some are obviously darker than they should be.  The adjacent wall material seems to matter not and isn't affected. ---Jovet 09:40, 28 July 2012 (UTC)

 * Also having this problem. All the common sounds are noticeably quieter; here is a list of files from the "resources" folder that play quieter (sometimes so quiet you can barely here: /random/pop.ogg (my favourite one!), random/splash.ogg and /liquid/splash.ogg don't work if you jump in (if you walk or fall it's fine), /portal/trigger.ogg doesn't but I don't think it ever did, and everything in /step/ (which I think includes break/place sounds, because those don't work either).
 * I don't see half the stuff that you mentioned in the resources folder anyway only /step but the volume issue makes it extremely unpleasant to play the game. It is especially jarring when you've been walking on wood or stone and step onto grass and the sound is loud because you'd turned the volume way up. I also miss the pop sound and the sound of block breaking. I really hope there's a fix for this soon! I want to start a new 1.3 world. --Tseotet 16:28, 28 July 2012 (UTC)

 * Do you find that updating LWJGL causes errors in window size scaling? When I increase the window size with LWJGL active (doesn't include before logging in, that's when I can change the size), the view magnifies. The screen also flickers, unless in fullscreen.

 * This bug was not related to the "Unknown command" display in console; I have been following this bug since 12w25a and was never aware of that having been an issue. The problem is that when an in-game non-op player tries a command like "/custom", no message whatsoever displays on the console, which is a regression from v1.2 and earlier behavior. --Warr1024 17:29, 26 July 2012 (UTC)
