Oh I hadn't realised it had! I'll have to make sure I update before I play again.

The release notes seem to cover lots of specific crashes, but I'd guess my issue is more generally that if it's trying to shoe too much stuff on the screen (like a crowded city) then it crashes. I have turned the graphics settings right down and it happens less, but still happens at least once each time I play. I'm keen to check out that patch and see if it helps. Thanks for letting me know about it!
