I wanted to test new files but it seems that my motherboard have died again...
Anyway, here's what you can do for a quick testing...
Start new Western Approaches campaign using silentotto cheat and exit to main menu. Then enter the museum and go trough the entire British and German roster but skip new C3 ship. After you're done with units rendering jump to previously skipped c3 . If game CTD then something is wrong with c3 controllers and they have to be re-saved in goblin.
