For the record, since I don't see these mentioned anywhere else:
Shift-clicking from a macerator/extractor (and I'd assume others, I don't have anything else made yet) causes the server to crash with the following exception.
Code

at ce.run(SourceFile:417)This may be because I have all of BuildCraft 2.2.5 and RedPower 2.0pr3b installed, but probably not considering IC2's colourful history with shift-clicking. 
I'd test out other machines/without other mods but I don't have time right now. Anyone else notice this?
