@MelodyAnimations Well since this isn’t a big wig company project auto-updates are kind of difficult to implement. Normally we are announcing the updates on our social media plus on the “news” section of our website.
Also last time I told you to try and keep at least some backup files. It is important so you can avoid issues like this. To be honest I feel a bit guilty that we can’t help further, but it’s really difficult to create a way to recover those files without more people helping.
If you want why not try Krita (http://krita.org) ? its a bit more stable and has an autosave feature too, but the files don’t get corrupted as easily. And you can animate and paint in it. Then you can export an image sequence, import it into Pencil2D and then make the final video.
