Nah It's not a tesseract issue, I think it crashed When I tried to put something into a chest at the same time, literally the same tick as the pipe was putting something into the chest. Ill try the Item ID fix, gonna suck a bit, but could I change it load the game and change it back and have all the pipes change back? I wouldn't lose much of anything with the pipes clearing.

Love love love AE systems the only problem is the resource requirements to start one are pretty steep when you are starting and buildcraft always "seems" more accessible because it is resource cheap but designing an efficient one is problematic. I miss the ease of Pneumatic tubes.

Is there any way to fix this kind of error? -- Head -- Stacktrace: at java.util.HashMap$HashIterator.nextEntry(Unknown Source) at java.util.HashMap$ValueIterator.next(Unknown Source) at buildcraft.transport.PipeTransportItems.moveSolids(PipeTransportItems.java:265) at buildcraft.transport.PipeTransportItems.updateEntity(PipeTransportItems.java:229) at buildcraft.transport.Pipe.updateEntity(Pipe.java:173) at buildcraft.transport.TileGenericPipe.func_70316_g(TileGenericPipe.java:189) -- Tile entity being ticked -- Details: Name: net.minecraft.src.buildcraft.transport.GenericPipe // buildcraft.transport.TileGenericPipe Block type: ID #517 (tile.null // buildcraft.transport.BlockGenericPipe) Block data value: 0 / 0x0 / 0b0000 Block location: World: (321,63,159), Chunk: (at 1,3,15 in 20,9; contains blocks 320,0,144 to 335,255,159), Region: (0,0; contains chunks 0,0 to 31,31, blocks 0,0,0 to 511,255,511) Actual block type: ID #517 (tile.null // buildcraft.transport.BlockGenericPipe) Actual block data value: 0 / 0x0 / 0b0000 Stacktrace: at net.minecraft.world.World.func_72939_s(World.java:2196) at net.minecraft.world.WorldServer.func_72939_s(WorldServer.java:546) It happens just after world load so I can't change anything, it is a SSP world.
