It happens both when I save and when I hit "continue" -- for some reason the game already comes with what it believes is a save file.
Ok that's really weird but that's something I can still try to solve. Thank you for bringing this to my attention I will try to fix it very soon!
I tried a few things but since I can't get the error, I don't know if it's fixed, but I uploaded a new mac build with my fixes so hopefully that solves the issue!
