crash report: http://hastebin.com/raw/furezekati

This specifically happened to me with the Redstone Extractor. After the server came back up, the generator produced perpetual power, which was nice, but I don't want everyone crashing my server to get unlimited power :p

Whoops, not sure why that link isn't working. Looks like it is the same issue though, thanks for fixing it!

Can't seem to access the link, however I think this may be a duplicate to #122 in which case this is already fixed :)
