Dunno if this will help those of you who are still experiencing crashes on Windows, but this is what I figured out:
Downloaded the newest release (first time playing the game). I'm using a low-end ROG laptop with Windows 10 Home (64x), a dual GPU, 16GB RAM. When I run it on integrated Intel mobile GPU it crashes about 10 minutes in. I switch it over to my Nvidia card and it runs fine. Thought it odd for a game with such low-end graphics. Maybe it's putting too much of the calculations on the GPU instead of the CPU?
I also had it crash with the Nvidia card when I go to overwrite saves sometimes.
Really enjoying the game, though. :3
