Herman joined my group easily with no problems. However, after going through Bleakfalls Barrow several times trying to find the Dragonstone which was now missing, I went to talk to Herman, wondering if maybe it was in his inventory, all things in his menu except for asking for his advice and asking him to follow me disappeared. He then started walking away from me. I asked him to follow me and he agreed but then kept walking away from me. I tried several times and even summoned him but he continued to walk away until he got to the campfire. Then he'd just stand there. Help, I really like this mod but I can't resolve this problem.
