I ran into the Paulette ZS crash a few times. Later, I had to leave the game in the middle of a scene, and when I opened the game again a few hours later all of my save data was completely gone.
Yep, this is just a thing that your device can opt to do when it feels like. Now that I've fixed this for Electron, I'm looking into potential solutions for Cordova too.
And like that, it is done. Hopefully this should make android save data more reliable in the future. There's a few polish things I think this needs but it works.
