Tried to run Company of Wolves (Ravenloft weekly) today, and was directed to speak to someone at the first campfire, who wasn't there. Tried to carry on round the map, but kept directing me back to the campfire. (not the first week I've run it, and normally without incident)
Thought I'd log out and back, but same problem. Decided to abandon the quest and pick it up again to see if that fixed, but can't take it again this week.
