Update: I am at a loss. Almost certain this is a bug. So I opened the same file mentioned above, go to the space center, and examine both craft in orbit. Indeed one of the kerbals is an engineer (we are a sorted bunch to say the least). So I think to myself, 'great, I am just an idiot...' I tested SAS just to make sure I wasn't crazy and sure enough, no motion. Then for some reason I decided to open and close my docking port and suddenly.... SAS!!!! What is going on? According to some comments above, that shouldn't happen. I had been flying this kerbal all over the place, even used him to land on Minimus. I would move this to the support forum, but I am not able to reproduce the issue now. If it pops up again, I will snag that message and any other info that I think might help.
