Computer cheating me of victory

[Seth Buttercrump]

I'm playing SHIII with GWX 3.0 and in my current campaign am up to feb 45, and my latest save position is an attack on a heavily defended convoy off the coast of East Anglia.


I have had the usual CTD save issue before, but now the game is crashing when I hit the 4th destroyer, as pictured. As soon as the torpedo hits, regardless of the viewscreen, I get a CTD.


Any clues?
