That is one of the problems with the game. You get assigned the mission prior to docking upon your return, so you actually would have to go back ~two~ patrols, and transfer. You are, I think, the 3rd person now running into this. This makes me think it might be more than just the TaskForce that spawns in (literally ~IN~) Atoll area, so I'll double-check the assignment for those date time frames again. It crashes just when it would say "No Mission Too Difficult", correct? We hope we have that fixed in this next release. We shall see what we see when we see it...
