I have a broken quest from the thives guild in Riften. I had done Kill the leader of Uttering Hills Cave a long time ago and now I can not start Summerset Shadows because I have already completed Kill the leader of Uttering Hills Cave. It seem to be a bug that if you do Kill the leader of Uttering Hills Cave before you do Summewrset Shadows it bugs out the thieves guild quest; I also have no save from before I did Kill the leader of Uttering Hills Cave because it was so long ago. Can anyone help me out with a work around or fix for this one? Please someone help I can't advance the progress of the Redflaggon and get new vendors down there with out doing the special assingments from Delvin Mallory.

Crap sorry thought I was in a different sectiuon can someone move this for me. Thanks.
