yeah i've had that same problem to. i havent tried all different types of bandit hideouts but the sea raiders hideouts north of Ov i know for a fact are bugged. After running into this error the first time after accepting a quest to destroy the hideouts both sea raider hideouts were bugged preventing me from loading in. I then went and made a new character same faction and all that when back up to the same area (around Ov) gout the quest form Ov to kill the raider highouts and still was bugged. So seems to be less of a random bug and more of a fixed bug since i was able to have it happen twice.
