Sanctuary got attacked by raiders. When it was finished Trashcan Carla was in my best power armor. I always leave my PA without a core in them, but she still got in it. So I can't pickpocket the core, because there is none in it !! Guess it's a bug or did something change and can some people use the power armor without core ? Luckily I had a recent savefile, but how to solve it when it happens again. Talking to her does not work, no option to make her leave it like with settlers and followers.
