Hi I just upgraded to diamond and updated everything, and it gives me error message saying to ask a dev about it, it says “the profile for the user is a temporary profile” 
It seems like you’re trying to mod a game with an invalid savegame file. Try selecting a different savegame file from your device. What tool is this happening in exactly?
ive been using horizon for a while now so i know how to use game modding part of it at least, which is the only bit i really use. the save game files go straight onto my usb stick i dont think its because they’re invalid files. gonna try post a couple of screen shots now
