No, not really.
What platform are you playing on?
Windows, Mac, Linux, Android?
If you’re on PC, are you using the itch.io launcher?
The Itch launcher has this weird interaction with Ren'py games where it will randomly erase manual saves on updates for no discernible reason. It's at Itch's end, so sadly there's nothing I can do to stop it from happening.
That being said, all your autosaves will still be there. Open the LOAD screen and click on the "A" down at the bottom of the screen, to the left of the page numbers. Autosaves trigger every time you sleep, so you won't have lost any progress.
Hmm, this is weird.
Not sure why itch.io doesn’t let the game write saves to the separate folder.
I have something that - provided you got the time - you should try.
At this point you should see a bunch of game versions.
So assuming you did find some saves, just move the saves folder over to the newest version.
