Oh, I've never heard of this error 😬 Do you save in bulk or by one save? (By bulk is through "export/import", by one is through "save/load" in the menu.) Or both of these don't work? What browser do you use, and have you tried others?
So while I’m playing the game I do one save. So I can go back and do as many routes as I want. But when I’m done I export the one save to my files so I can import it back into the game when the next update comes out. One save works fine I just cant import bulk saves anymore. Im on IPhone. So mobile browser? I haven’t tried on my laptop though I can give that a go.
