Minecraft was updated to 1.7.3 the following are from the change log for this update, it was just a bug fix release. Bug Fixes: - Corrected a block duplication bug when using pistons. - Corrected a redstone torch duplication bug when using pistons. - Corrected a client crash when placing a sign in front of the piston, powering the piston and then removing the block beneath the sign. - Ice blocks are now pushed without causing water streams breaking everything. - Booster rails are no longer being powered magically without a power source . - Pistons connected to the end of a piston transistor via redstone are now properly closed when the power goes out. - Doors no longer create purple particles. - Hacking clients can no longer edit texts of placed signs in multiplayer . - Changed so that paintings pushed by pistons will pop off. Server News: We have updated Minecraft Server to the latest version that was released on Friday by Mojang the server is now running version 1.7.3, this update was supposed to correct a number of piston bugs and it appears to have fixed some, but not all. We still experience read timeout errors under certain situations, after investigating the logs it still shows pistons are the cause of the crashes, so steps have been taken again to stop the use of them in game until all issues are resolved and the server is stable with them enabled. Just for players interest I have included part of the crash log below. 2011-07-10 20:08:04 [SEVERE] at net.minecraft.server.TileEntityPiston.a(SourceFile:100) 2011-07-10 20:08:04 [SEVERE] at net.minecraft.server.TileEntityPiston.g_(SourceFile:145) 2011-07-10 20:08:04 [SEVERE] at net.minecraft.server.World.cleanUp(World.java:1124) 2011-07-10 20:08:04 [SEVERE] at net.minecraft.server.MinecraftServer.h(MinecraftServer.java:447) 2011-07-10 20:08:04 [SEVERE] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:361) 2011-07-10 20:08:04 [SEVERE] at net.minecraft.server.ThreadServerApplication.run(SourceFile:422) 2011-07-10 20:08:04 [SEVERE] Unexpected exception java.lang.NullPointerException at net.minecraft.server.TileEntityPiston.a(SourceFile:100) at net.minecraft.server.TileEntityPiston.g_(SourceFile:145) at net.minecraft.server.World.cleanUp(World.java:1124) at net.minecraft.server.MinecraftServer.h(MinecraftServer.java:447) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:361) at net.minecraft.server.ThreadServerApplication.run(SourceFile:422)
