Minecraft will crash when playing a LAN game.

i don't know alot about this and i don't know if it should be here but when i restarted my game one time,all my saves were lost but there wasn't a crash

[!] [SMP] Windows When placing a firework on any block or launching a firework from a dispenser, the gameplay ends and kicks the player out giving a error stating "End of Stream" or "Internal exception: java.net.SocketException: Software caused connection about: recv failed".
When trying to log back into the server the client gets rejected immediately saying "End of Stream" or "Internal exception: java.net.SocketException: Software caused connection about: recv failed".
The only way to get back into the server is to shut it down, and restart it. Upon reentry to the server, the firework is gone.

The error is consistent any time a Firework is placed or launched from a dispenser.

This is a Windows XP Professional 32-bit minecraft server at home with no mods or added textures. The server is upgraded to version 1.4.6, the clients are upgraded to 1.4.6, and Java is upgraded to the latest release version 7 update 10.

EDIT: This problem is fixed in update 1.4.7 KRaSh197997 13:39, 3 January 2013 (UTC)

[!] [SMP] macOS Linux Above Bug is reproducible on OS X MineCraft client 1.4.7 with the server running on a Linux server. Rebooting the server does not seem to help. jimmodo 09::24, 9 January 2013 (PST)

[!!] [Cr] Windows This is a bug that happens on some old windows computers. When you open your creative inventory, closing it will crash the game. Fix - delete everything in your bin, and then force update. --KrapTV 18:00, 2 January 2013 (UTC)

[A!] There is a major annoyance when you try to update then later use an older client. I tried to update to 13w01a and then tried to downgrade it. This failed horribly and now I'm stuck with 1.4.6. --ChilledEnderman 07:24, 4 January 2013 (UTC)

[!!] [MP] Linux Totaly random, but every on X hour 24minutes 0 second , all players are disconnected, can't join until four to twenty minutes, with nothing more than "Connection Reset" in server logs. 03:05, 7 January 2013 (UTC+4)

[A!] [MP] Known onmacOSWindowsRandom, when attempting to connect to a server you do not connect and are sent straight to the Main Menu screen and then when you try to connect it says "Connection Error". Must restart Minecraft to connect to the server. Tested on: a1.mc-sabotage.com, kitpvp.us, mc-war.com, epsilon.oc.tc, beta.oc.tc, hg.minecrafthg.com,, sg1.mcmn.eu, mc-hg.org, wallsmc.com, eu.spleef.in, skywars.co, ctf.vaultcraft.com, mc.massivecraft.com, mcctf.com.

[X] [A] When creating a new superflat world (with any seed inputed by the player), minecraft crashes. The world is fine, and does generate with the chosen seed. This does not occur when you do not input a seed into the seed generator (when it is random).



Certain items will reappear and disappear in your inventory.

  • Not enough info to recreate

[X] When I place a boat on ground, push it, then enter it, it falls through one block. --Conscripta

[X] Powered booster rails sometimes act as though it is not powered

[X] Pigs/chickens crash boats. I find this quite annoying

[X] [MP] When breaking a block the cracks reset. --Minecra21212 22:13, 30 December 2012 (UTC)

  • Moved to Annoyances --Minecra21212 23:01, 31 December 2012 (UTC)
  • Moved back to Bugs. The cracking animation is supposed to transition smoothly from one image to the next. If it does not, it's a bug, regardless of how trivial it may seem. E-102 Gamma 08:09, 9 January 2013 (UTC)


[A] [MP] The player cannot send out messages until re-logging the game, there is a little rollback after re-log. --SamuelTangz 18:33, 4 January 2013 (UTC)

[A] Tested in [SSP] When either anything is held/nothing held whilst going into and out of water the item/hand moves up and down on the screen. Tested using water/air elevator.

World generator[]


[!] Upon spawning, you get stuck in the first block spawned on.--Aerotactics 08:51, 31 December 2012 (UTC)

January,2 time:3:35 [!] Another bug is if you make a custom superflat world with only 1 layer of gravel (nothing else),when you spawn you will fall thru it and into the void without the gravel falling.

Discovered by:dpetta10 "Happens in every gamemode and both singleplayer ad multiplayer."


[A] when generating world with bonus chest, if ground is uneven torches will drop as items and if a chest tries to spawn where a block is sometimes the chest is not there but dropped items typically contained in a bonus chest will be there



[!] Mobs still 'float' in the top layer of ground, being partially submerged.--Aerotactics 08:53, 31 December 2012 (UTC)

  • For me it only happens in multiplayer. --Minecra21212 23:04, 31 December 2012 (UTC)
  • It happenes to me in Single player. --Aerotactics 01:22, 1 January 2013 (UTC)


[A!] Mobs will randomly stop taking damage while in the middle of combat and do not take damage for about half a minute.-Power_625 01:07, 31 December 2012

  • I have seen this with other players as well, in addition arrows fired at the target seem to not launch or leave the bow. In fact it almost acts like you never fired the arrow -Rambo828 09:07, 02 January 2013 (EST)
