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.
- Go to the game’s page in the itch.io launcher.
- In the bottom-right corner, click the gear icon.
- Click the button that says Manage.
- Click on Open folder in Explorer
At this point you should see a bunch of game versions.
- For the sake of this example, let’s say you updated from 0.19.6 to 0.19.7 and your saves went missing.
- You go to the folder for the 0.19.6 version, inside it there will be a folder called game. Inside of that one you’ll find a folder named saves.
- If you see inside a bunch of files with numbers in the name and .save file extension, then you’re good. If you don’t, check another version’s folder or resign because you lost your saves.
So assuming you did find some saves, just move the saves folder over to the newest version.
