Tuolumite

So I've advanced in game to the point where Dr. Tully starts following you around and when I was gathering some charcoal chunks he got stuck. He moves around a little bit but he's just running into one of the flaming charcoals and won't change direction. It's been over a week now in game. I've tried moving all around the map, sleeping and reloading my save a few times. Is there any way to get him unstuck?
