DEV bug fix, if in a process a condition is identical to an action (meaning nothing changes on that site if the process is executed) the otf logic activates a process again, even though this process is already active beforehand. This leads to processes activated twice. This double processes lead to a program crash because if this double process is deactivated only one is deactivated and the other one is still  activated but an illegal process in the system. Fixed by filtering out actions which are identical to conditions.
