Hi. Which version of the game are the saves gone? Do you mean the latest update or before Chapter2. I’ve made some changes to the game that made the save from before Chapter2 incompatible which I’ve talked about in the post. But the purpose of that is because the saves were handled poorly before that(a lot of bugs with variables) that I was able to fix for Chapter2, and should work better with future versions. But if you mean the saves are just completely gone, then that’s unusual. Since updating the game will not do anything to your save files(They should be in a completely separate folder from the game.) even the incompatible saves should still appear on your Load screen.
That being said, I am looking into what caused this. But it is definitely not intended. So sorry for this.
