Had same problem and used the fix which seemed to mostly work. I had a terror mission in a small office in italy and when I would try to do the mission it would bring the map loading screen up and then kick me back to world view. I would pull my dropship out and in trying to get the mission to work and it kept sending me back to world view after showing the loading italy map screen until I gave up and let the terror misison go and went on playing the game. No other bugs. Great game by the way.
