Hate to be "one of those guys" but "I also have this bug". Minus the quest thing that is, he still gives quests and I still get settlement updates, its just preston and the other 4 decided to slide on back to that sweet museum of Freedom for no reason, and now they won't leave. they TALK about leaving, but they wont actually do it. It's mostly just annoying rather than gamebreaking for me, because they are still registered as living in sanctuary. Things I have tried - placing preston in sanctuary with console (doesn't help, only copies him) -making sanctuary have no issues (removing the warning symbol in the workshop tab of pipboy) result: they dont care, the museum is nicer I suppose... -completing all quests for preston (don't know why I tried this but it didn't help) Any suggestions on what else to try? Assume my gamefile is the same as yours, working as intended, except preston thinks he is supposed to be travelling to sanctuary but wont actually do it.
