I finally summoned up the courage to do my first group dungeon. I was having fun then it crashed to desktop. When I returned I was in a grey limbo and my character was screaming. I did /stuck and used a soul gem -> same limbo. I had to use the way station death. However, the group was nearly finished and there was still an objective of 'Get the chief's head'. However, the goblins were all cheering and there was no head to be had anywhere. How can I complete the quest?
