It just adds a block of code to an existing script. All the previous states are still valid, though it's possible the new state is not recognized by other scripts.
I don't see how any script that deals with the interface is dependant on the "crew state" of an AI ship though.
Try it on a stock game, see if it works.
Anyone else experiencing issues? Or not? Would like some feedback either way, see if it this is an isolated case or widespread.
If anyone is still using it in case of massive fail, of course.
