I hit the same problem with T3 in the fuel depot area. Couldn't get him unstuck, so I shut down for the night. The next morning I went in and he moved fine.
Also, this morning I got stuck with my character in the tunnels. He got stuck on a corpse. I tried the shutdown thing again, but this time it didn't work. Somehow I managed to hit on an odd combination of forward and side movement, at the same time and right direction, and he came unstuck.
I'm feeling rather fortunate and/or lucky right now. Hopefully, this will be addressed soon.
