Game Centre was calling other players by their game name. I.e. I was .Confused.
Now, it calls people by their real name (i.e. I'm now Philippe, for you, i think. For me you're Brian, Jean-Guy and Adolphine) in the invites, but Spellcraft calls people by their game name.
That gets .Confused. quite confused, as i used to know people that i really still know, but can't recognize because they don't have the names i know, but the names they really have. This is even worse when people don't have pictured circles next to their one-name-or-the-other, there is no memory bridge at all!
GC is calling you names. What can I do about it? I'm mustering my footmen.
