Did he load an older save after updating the quest file? This usually happens under those circumstances as a result of global variables getting shifted around and the map system not knowing how to react.
I hear a lot of buttons getting pressed, but if I wonder if he ever pressed the space bar or map button on his controller. With any luck, this is a map glitch and the map could be dismissed by pressing that button. But if it is the save file issue above, other scripts would break, too.
It's also possible that he saved with the map open, which would have kept it open when he reloaded and somehow resulted in it not getting populated by the right rooms. Again, hopefully pressing the map button would fix it, and his save would play normally from there. I'll try to put something in to dismiss the map on reload.
