I downloaded the Traitor's Keep DLC and i started the quest. I'm still going through the "Pit" and I was fighting the (i think) 3rd group of prisoners after jumping down and helping his guards. I need to keep going, but the game wont let me walk through a door to get to Hobson and the main quest guy.. It says to defeat the prisoners, but I already have. What do i do?? I really want to keep going and not restart because ive completed the game, acquired massive amounts of money, and I can't fast travel anywhere due to a quest.
Have you tried reloading the save and trying that part again?
