I can now report a constant, repeatable CTD after winning naval battles. Auto calc is fine, but I have fought 6 battles today, and 4 CTD after I won. Strangely, after restarting and fighting the battle AGAIN, no crash happend the 2nd time around, or during other naval battles I fought after the restart. It seems to be only after a fresh start of the game, very odd.

This is with my Vista 64
