So apparently, I'm shadowbanned from my!castle. I still can access PvP and others castles, but they can't visit mine, as I tried to access my castle from my other CQ cartridge.(Which btw, every copy of Fates has a different castle address number.)
I didn't have any units in illegal classes in my castle team, although Kana(Who was not in the castle team) was a Nohrian King. I'm not sure if that caused my castle to get shadowbanned, or perhaps something else.
But, is there a way to get unshadowbanned? Do I need to change my units and Kana into something else, or delete the save data?
