Hi,
I think I have an idea what's been happening (save games in the game folder + app "upgrading" your game install to the demo version because it's more recent + there's no clear way to track upgrades unless the game is uploaded with butler).
To confirm that, can you send
- 1. The contents of the %APPDATA%\itch\logs folder
- 2. The contents of the %APPDATA%\Roaming\itch\cave-logs folder
- 3. A list of the games you mean by "all my games" - specifically, the games you've noticed the saves of disappearing
to the support@itch.io e-mail address? (these may contain data that's unique to your account, so it's best not to post them publicly).
If my intuition is right, that bug will no longer exist in the next major version of the app. In the meantime, I'm really sorry this issue affected you and I wish I knew about it earlier!
