That's really strange. Is XD9 you in-game name as well (you can answer in a direct message if you do not want to disclose this publicly).
Yes, I log in w/ xd9, and what I see when I'm in game is XD9 (note the in-game shows as with capital letters, not sure if that makes a difference). If it helps, at one point many years ago during the shuffle-it days I think they had my email address associated with another username, I can't remember it but it was something like XD9-2- or something that came about from some problem I don't recall. As it is now, I can't include original deck cards in my games as the host, let me know how I can help solve the issue?
