I dunno if the comment is meant to be rude or not but it's coming across that way.
I was already being careful, as I said it's happened multiple times across 4 different restarts. It doesn't matter how long I wait between changing screens the saves will break no matter what. I could've saved over 5+ mins ago and it will still do it.
If it's a problem with the program itself and will never be fixed, fine. I'll just wait until the game if finished so it's stable, it's what I was going to do anyway if the issue persisted in future versions.
