Hey @Multby6 not a huge issue for me since im more tham happy to play the whole game again but when i was trying to update from 4.0-5.0 i got this error through. (Android)
Hello! Yes, there is an option in the settings to restore corrupted saves I couldn't find a way to avoid this error, so I just gave players a free save file if you go into the settings you can restore a v0.4 save that has all the progress up to that update completed!
