Before I was aware that there was a multiplayer, i thought it was an Easter egg of sorts, but when I chose my Female Clerics name as Jallarzi Sallavarian, the game changed it to Eustace! Is there a list of taboo names for copyright purposes or something?
Are you sure it's the same character? When Gary introduces MP, he gives you a starter deck with three new chars and equipment. Your old chars should still be present off to the side. Or are you trying to change her name? There's a bug where name changes don't save until you leave the keep.
