I too am experiencing CTD with WTF.dll and CoherentUIGT.dll. One or the other happens on almost every flight with the A350. I can't even remember the last time I had a successful flight from takeoff to landing. Oh, looked it up, have had one successful flight in the last week, and I'm flying every day.
Version 1.0.8. I don't have Autosave enabled.
It's frustrating.
