I've cleared out the prison. I've cleared out the main building. I roamed around outside the fort looking for any sort of back/side/underground entrance and wasn't able to find anything. I hopped back and talked to the original quest giver, who tells me to hurry up and clear out the Fort. I waited in town several days, hopped back out there, and nothing. I googled, but didn't see anything noteworthy. In fact, I didn't find much of anything about the quest period, leading me to believe this is unique to me, or that I've missed a spot somewhere. I get no markers, the quest log simply says, "Clear out Fort Hraggstad".
I'd prefer to get past it legit-like, but if it is, in fact, bugged out then I'm not above cheating. I've been browsing the console cheat lists I can find, but can't find any that would help me advance my quest.
Any ideas? Apologies for what may be a dumb question; I'm sure you see your fair share here.
