I'm having repeatable crashing errors with Settlers II History Edition (purchased via the History Collection). In mission 4, having expanded to several different islands, the game repeatedly crashes to desktop at shortly after the 7 hour mark. Every time I load the save file, it crashes at exactly the same point.

Is there a fix for this? I'd hate to have to abandon the campaign after putting so much time into it!
