The hanging is frustrating in ways I didn't think possible. If you are playing timed missions and you hang, the good news is, you will be restored to the last point that you were at. The bad news, is the timer doesn't stop, it continued.
I was doing the Lincoln memorial, and had progressed to the area before getting the plans and closing the tunnel and I was at 7:12 (of 12:00 for top score)
after the hang/taskman kill/cloud sync to get to where I could restart, restart, go through the startup disclaimers, etc, got back into the game and now I am at 9:32. If you think, oh, let me try starting another timed event, then jump back here... Nope, you will again continue at the last point and the timer won't reset. This is another instance where, through no-fault of your own, you are being penalized.
