Everyone be warned. If you start a sidequest make sure you finish it before you turn the game off. I started the Frontiersman quest UFO in Boston and had to shut down my game. When i returned to play the clue markers were gone and now i am no longer able to do ANY frontiersman missions. It shows the map marker for the missions but when you enter the pubs you can do nothing but play the pub games. I've tried quitting and exiting the game through the menu, shutting down the xbox. I even did the next main storyline and it still wont work. Do i restart the game at 55% complete and forget those missions? Nope. What a pisser.
