Someone left a factory on .2 seconds...
People, please remember to turn your things off when you leave, and do not ever set timers that low. I do not want to institute lag-machine rules (was hoping common sense would be sufficient), but will if things like this continue to occur.
And a word of warning to all potential MCedit users: backup before you do edits. I was looking for lag sources on the map last night when MCedit crashed and corrupted the map. FORTUNATLY, I make backups of backups of backups, so nothing was lost.
