[Bug 1.64 SMP (bukkit)] Compressor+Pump = NPE

Hi folks,

Using the bukkit port so please let me know if this is not an IC2 problem. I placed a compressor next to a pump to make snowballs. When the compressor got to 100%, NPE as follows. Happening on subsequent reboots so looks like I'll need to revert to a backup.

edit: Same problem happens in single player (so I'm thinking IC2 problem)

java.lang.NullPointerException

Already fixed for the next release.

Tends to corrupt the saves (you are free to load them after updating IC2 if the new version is released).

Fortunately with this one I knew exactly where the offending compressor was so I was able to delete the block with MCedit. Glad I didn't need to roll back!
