This is the biggest frustration with the game, GWX or stock, then combine it with the fact that it takes 10 minutes to load and it really gets frustrating.
I have noticed that if you revert to the previously saved game, then you're usually in good shape.
One thing I have noticed as well, or maybe its just wishful thinking is that after I pull up a saved game that has CTD a few times, if I change something Ex depth, or course or speed, or crew management, sometimes it will go ahead and not crash.
Mine crashes everytime I tried to load the last saved, so as mentioned I save as Im approaching a victim, then I'll go ahead and start the attack, and save again. Should it crash at the attack, I have the saved game whenI was approaching the target.
Clear as mud? Good
