Hey, I'm not aware of any crashes that could happen so often, especially during saving. The Steam version has been updated with a few fixes that will make it to itch.io very soon, but I don't think they'll change anything. But you can get a steam key if you bought the game on itch.io. Do you have a save file that causes the game to crash soon after the game loads it? I would love to see it. Feel free to email me at miki@keeperrl.com
