Hmmm, that looks like it's on Android or iOS. Did you edit the settings file externally? That could be what's causing it
First of all, that's an incredible amount of plays haha well done! But I tried to recreate this bug, but I haven't been able to. It looks like based on the error message, the save file is not being found or loaded properly for some reason. I really don't know what could be causing that. Are you playing on Android or iOS?
