itch.io

What platform are you using?

How did you install the new release?

If this was via the Itch auto-updater then sadly that's something that can happen randomly (I have no idea why, it's an eccentricity with Itch's methodology and nothing to be done at my end, sadly).

However, for some reason it leaves the autosaves untouched! So if you open your LOAD screen and tap on the "A" at the bottom-left, to the left of the page numbers, you will be able to reload your autosaves (which are recorded every time you sleep).
