Just to clarify, you're saying you have the 5th motor electrically plugged in and wired in at all times. With the 5th motor wired in, your code works if you don't open a reference to it, and everything stops working when you do open a reference. So the only difference is you changing the code, nothing electrical. Is that right?

Also, what are your diagnostic light on the dashboard doing when the robot doesn't work? Do you have comms? Robot Code? Are you getting a watchdog error?

Posting your code would also be helpful for trouble shooting.
