Im experiencing a simular problem. It happend somewhere in act 2 when i went back to my Stronghold, i suddenly got the ghost at the front of the keep door screaming about the fire, wich occurs when you first enter. The door to dungeon below is now locked, tells me i need a key ,and the Steward does not talk,even though the Keep functions in the menu still work. The game works fine in areas i have not been in yet, but when i go to an already visited area it resets parts, but not all of it. In Raedric's stronghold, the black fog is back, the guards are not hostile but all the door that were open before need to be re opened and lock picked and Raedric, who i killed, is sitting on the throne but i cant interact with him . I really hope i can finish my first playtrough of this game this way, as it hasnt blocked my path yet, but i fear for the worsed if i have to go back to the Raedric's at some point of the story.
