I have a CTD too in the manche channel (between france and uk) sorry for my bad english. But, it's not always crashing so I can still play.
But I have another problem, is the sea that reset itself, quite often... for example I have bad weather, heavy clouds, rain, rough sea... and suddenly everything becomes clear, no clouds, calm sea, and in couple of minuts/seconds the weather come back. It's quite surprising and unrealistic for the crew
