Here's something I've never seen before. I was setting up to take panel flats. The AutoFlat script was running and ACP was driving the rotator to the proper PA. The display in the ACP Console clearly showed the rotator changes in Sky/Mechanical angles as it rotated. Yet ACP went right by the correct PA, rotated 360 deg more and went by it again. At this point, since I was watching, I shut everything down, manually unwound the cables to the rotator, rebooted ACP and started over. This time it did stop at the appropriate PA. GNS did time out so that alert did work. I'm not sure the logs will help since I think they'll only show "waiting for rotator." This is a little concerning since I'd hate to rip the cables out of the camera, etc.
