I was playing on my main save, looking for Daedric artifacts to get and realized I was missing the Ring of Hircine. My problem is when I went to the barracks in Falkreath, the guy (Sinding) was already in his wolf form and when I tried to talk to him, he wouldn't say anything.
When I spoke to the guard he said he knew I had something to to do with Sinding's escape, even though I never even played the quest on this save before (I've done it on another save). I've checked my completed quest twice and I don't know what's wrong? How can I start or advance the quest at this point?
