  1. I made an infinite geothermal generator on my server using an energy condenser and piping. Whenever I try to start it up, I get this error report. 012-03-02 20:30:01 [sEVERE] Unexpected exception java.lang.NullPointerException at net.minecraft.server.ItemStack.doMaterialsMatch(ItemStack.java:243) at ee.TileCondenser.extractItem(TileCondenser.java:539) at buildcraft.transport.pipes.PipeItemsWood.checkExtract(PipeItemsWood.java:111) at buildcraft.transport.pipes.PipeItemsWood.doWork(PipeItemsWood.java:90) at buildcraft.transport.TileGenericPipe.doWork(TileGenericPipe.java:159) at buildcraft.api.PowerProvider.update(PowerProvider.java:52) at buildcraft.transport.TileGenericPipe.l_(TileGenericPipe.java:108) at net.minecraft.server.World.tickEntities(World.java:1182) at net.minecraft.server.MinecraftServer.w(MinecraftServer.java:534) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:441) at net.minecraft.server.ThreadServerApplication.run(SourceFile:465) I can tell it's a problem with the piping. It's a small server I play with friends, so I don't have any good backups, and they'd be really annoyed if the world completely broke. Is there any way I can make the world file work again?
