I just downloaded OpenBlocks-1.7.10-1.4.4-snapshot-664 and I was greeted with this crash: http://pastebin.com/RH8ih2SD

note: I have Elevators disabled in my configs. When I disable also the Elevator Rotating in the config - crash no longer occurs.

I understand it is because Elecator rotating is dependant on normal Elevator. But maybe in future if the Elevator is disabled, then automaticaly disable the rotating one (if possible)

That was typo in already existing check. Elevators will stay separate in config.
