Hey, any change in the situation? I'm having issues with the same bug. It wouldn't bother me much, but the my Sanctuary settlement is getting killed by it. I keep getting notifications about no food/water/beds (I have a ton of food/water/beds) while I'm outside Sanctuary. When I go back, everything is fine. I can't help but think it's related to your bug, since normally Preston and his buddies would be working/sleeping around Sanctuary, and when they're in the Museum of Freedom they can't. This causes the happiness in my settlement to crash & burn.
