No, I simply did the "normal" thing, killed the two raiders with the old man, talked about the raiders, sneaked up to the turret, hacked it so the 3 raiders in the halls got shot, cleaned up the level, and went into the main hall to fight the leader and his two friends.
Current version of course.
Not the first time it has happened as I said, so there has to be some kind of bug that is not fixed after all.
