In Passwater Cove, one my of experts is stuck trying to leave on a mission. She's stuck along with a few of the guests in the same area, with deteriorating needs, and cannot be picked up. I also cannot cancel the pending mission or sell my helicopter pads. I JUST rebuilt my museum, but may demolish the whole thing in a few days and see if that helps. The expert in question is one of my better ones, and I don't want her to quit.
