oh dang. I was unaware of that mac crash with the autosaving. (It's why it throws an error at the start of every battle) I'll see if I can fix that for the next patch. I didn't know anyone who had a Mac so I couldn't test it lol.
Thanks for the video!
EDIT: Alright, I'm pushing the patch now. Hopefully this fixes the crashes! Should be ready for download within 15 minutes.
