I’m not sure. My guess is that the save editing somehow broke Ren’Py’s own save validation/encryption, so it can no longer restore the save properly.
But that’s just my assumption — I’ve never really worked with save editors myself.
Hi! In the current version, unfortunately, there’s no workaround. The bug was reported to me and I’ve already fixed it, so it will be resolved in the next update, along with a number of other QoL improvements for Android.
Don’t worry too much about losing progress for now. The game is still in a very early stage, and quite a few things will inevitably be reworked based on your feedback.
