undefined Always when I'm push the open texturepack folder button minecraft freeze. I have to use the taskmanager to stop minecraft. Then the windows message appears java se binary don't react anymore (I think so, because my message is in german). This happens also in a new fresh installation of minecraft 1.2.5 and in all snapshots later. My system is Win 7 64 bit with the newest oracle java sdk 7u5 64 bit (not updated, new installed) and a fresh minecraft 1.2.5 installation. I have tested all java 64 bit versions since 7. Please don't write that it work for you, because I heard this before. I don't understand why this happens on my computer, I have a new Dell XPS Laptop and all programs fresh installed. --reptile311

 * Can it be a thing with the rights in Win 7? I have the minecraft launcher in a folder in the standard download folder from user (Hubertus, my username). Only the launcher .minecraft is in the roaming folder.

!!? Potential odd, but very serious crash. crashes ALL keyboard/mouse input, rendering the entire laptop/PC unplayable. game continues, while any buttons pressed remain pressed. Has only happened to me while playing Minecraft. Has only happened in a recent snapshot. I very rarely go in Singleplayer, so may or may not be multiplayer exclusive. while extremely serious, is fairly uncommon. I run a high-end Alienware laptop, so memory consumption is not a factor in my opinion. Can any other users confirm this is a Minecraft bug? --Kizzycocoa 21:08, 14 June 2012 (UTC)

a Some systems may experience a FPS drop since 12w18a varying from 10 to 3 fps when in 1.2.5 average was of 10-30 fps (My system specs: 32-bit processor, less than 2 GB or RAM, 512 MB Video Card, Windows XP SP2). --Manuelschi 17:22, 14 June 2012 (UTC)
 * My Mac and Win XP systems that I used, experienced the "connect" bug at that time, when the server first came with the jar. That bug itself has been fixed, but later effects are still there, such as lag, the recent lag with the game updating the level, and "Can't keep up!" issues. Also, this issue is more persistent on farther renders. --Wormy14 11:14, 15 June 2012 (UTC)

a User death messages are displayed in chat but not recorded in the server.log file. This can make it tricky to settle disputes on vanilla servers. --Darkinnit 20:22, 14 June 2012 (UTC)

a The console is heavily spammed with "Can't keep up!" messages, with kilobytes of logging data, making up 99% of the console log, and making it necessary to offset the log to save the CPU (automatically). Occurs even on lowest renders, but more persistent on higher ones. --Wormy14 11:20, 15 June 2012 (UTC)

!susp Mobs and entities are still periodically freezing. Exiting the world to main menu resolves this, but any progress made up to the point of freeze is not saved.

 * I hate this bug. If you wait a looooooong time, it will unfreeze. It is probably related to the server merge. --bcnjr5 11:04, 15 June 2012 (UTC)
 * I agree that it has something to do with the server merge because it first appeared for me with the 12w18a snapshot, which I believe is the first to incorporate the server merge. This bug has been there since.  I keep having to roll-back to the 12w17a snapshot.  I truly hope this is fixed before the 1.3 release, because it is a gamebreaker for me. --71.61.206.196 21:14, 15 June 2012 (UTC)

a The enchantments with "Protection" in the name besides Protection don't provide more protection to a specific thing than Protection does, making those enchantments completely outclassed by Protection. To make matters worse, you can only get one "Protection" enchantment on a piece of armor. TorchicBlaziken 20:41, 14 June 2012 (UTC)

a The player cannot swim out of downward flowing water while drowning. The damage taken produces a small amount of knockback, which in combination with the flow, keeps the player from swimming out of the water. --CaMoreno3 15:16, 14 June 2012 (UTC)
 * This is different from the behavior in 12w23b, as the player was unable to swim out of water (while drowning, regardless of flow) or lava at all. The player can now swim out of lava regardless of flow. The change leads me to believe that this annoyance has been addressed. Is the inability to escape downward flowing water intentional? --CaMoreno3 15:16, 14 June 2012 (UTC)

undefined When collecting Mushroom blocks with Silk Touch it will not preserve the damage value. TorchicBlaziken 23:49, 2 June 2012 (UTC)

undefined There are a few lines of code in the class for the End Portal block (the actual portal itself, not the frame) that prevent the creation of End Portals in the Nether or End except for like a split second after the Ender Dragon dies, even though this doesn't matter because you can't even make them in Survival. This only serves to prevent the player from replacing an End Portal in the End after a player in Creative destroys them. TorchicBlaziken 22:39, 7 June 2012 (UTC)

undefined When placing Mushroom blocks of a damage value greater than 0, it will revert to 0 upon placing. This used to happen with Monster Eggs, before they were tweaked in 12w17a to prepare them for inclusion in the Creative Mode inventory.

 * Stone Pressure Plate
 * Wooden Door
 * Iron Door
 * Redstone
 * Redstone Repeater
 * Rail
 * Powered Rail
 * Detector Rail
 * String (floats above upper slabs or stair blocks when placed)
 * Torches (including redstone torches) are placeable on stairs but not slabs, which is needlessly inconsistent.


 * That is intended, stairs and slabs are non opaque blocks, so you cannot put blocks which are dependent on a solid block. This should be a minor annoyance.EmanP 18:19, 14 June 2012 (UTC)
 * I disagree completely. This seems like more of an oversight than intention. Why are double slab blocks solid while Upper slabs and upside-down stairs are not? Both of these blocks are flush with all other blocks and should have the ability to have these items placed on them. The only reason they are transparent is for lighting, and even still lighting is buggy with them. This needs to be fixed for the sake of consistency. --CaMoreno3 18:28, 14 June 2012 (UTC)
 * Making these blocks solid would, as far as I know, make them act different in regards to redstone, in both good and bad ways. Redstonehelper 21:10, 14 June 2012 (UTC)
 * But, it probably would be possible to make it so that you can place those things on the top of a slab anyway, since they made it so you can place torches on upside-down stairs. TorchicBlaziken 15:00, 15 June 2012 (UTC)
 * It would be possible for some things, but I'm sure redstone would provide with some interesting weirdness. Rails would act different when interacting with redstone, as top slabs are not full blocks. I think torches should be allowed for consistency, but the other items should stay out to avoid confusion. Redstonehelper 01:00, 16 June 2012 (UTC)

fSince the world seed has been removed from the debug display and the /seed command requires cheats to be enabled, there is no way to view the world seed on non-cheats-enabled singleplayer worlds.--League 18:44, 14 June 2012 (UTC)
 * Workaround: Either use a mod to turn cheats on, or get into the habit of choosing a seed of your own whenever you create a new world. [I use the Mojang splash texts.] --82.69.54.207 19:59, 14 June 2012 (UTC)
 * just the fact that you know a solution to this problem doesn't mean it's not a bug. It should be fixed. but anyway. thanks for your temporary suggestion. --League 20:06, 14 June 2012 (UTC)
 * In my eyes that is absolutely intended to prevent publishing the seed of non-cheat worlds. Think of upcoming adventure worlds where the seed should be kept more or less secret to prevent cheating. As long as we don't have a clear statement of the developers if that is intended, it is just an annoyance, not a bug. --Kumasasa 20:19, 14 June 2012 (UTC)
 * You're looking at a very, very specific case, and assuming that Mojang chose it to take precedence over regular people who may not know that cheats on or off affects the seed display. Another possibility is someone doesn't think on world creation they wanted a fresh world or to share the world, but changed their mind later. Additionally, a save's seed is findable with resources such as the slime finder, making it trivial to find out a "secret" seed. Also, we can say something's a bug without developer statements. Upgraded to bug.184.166.122.245 21:28, 14 June 2012 (UTC)

 * Some language versions are identified by code (DK, El, IE, etc.), some by country name (Venezuela, España, etc.), some by adjectives (Français, etc.). There should be some convention in this aspect;
 * Some language entries are clearly redundant, like US/CA English, and UR/AR Spanish;
 * Joke/fantasy languages as Pirate Speak, Kinglon, Quenya are thrown together with the "serious" ones. They should be marked as such, since some translations border both joke and seriousness - a good example is Australian English translation, that can be viewed as racist if one doesn't realize it's a joke (where villager = "Bruce", cave spider = "Funnel Web" and furnace = "Barbie" and Statistics = "check ya stats?").
 * Also, in Australian English "You died!" is translated to "You kicked the bucket!". --177.3.48.101
