I used to update my catalog via PC. But I'm on my Wii U right now. it's showing my catalog as completely empty but it shows my total collected items under My Characters. Is it possibly because I'm on my Wii U?
I'm guessing it was due to your inactivity. Catalogs archive if a user does not log in for a specific amount of time (although I'm unsure what that amount of time is). I know the mods used to be able to unarchive it fairly easily, but I'm not sure if that is still possible.
Let's go Gophers! Ski-U-Mah!
Sorry, I don't accept random FCRs.
