NPC's are still going to my old base after i created a new base respite location is there anyway that this bug can get fixed? i have fast traveled to see if that worked and i also restarted the game and that still didnt work at all.... I'm not sure what to do from there.....??? Can you please help me out.
In the Cairn menu (hold E) have you force selected the new cairn as your respite?
Have you in the Cairn menu (click into it) in the top right tried "make town center"? Not sure that would help, but never hurts to try.
