So I logged on this morning and my whole friends list and real id thing was cleared and so was my whole friends list anyone have idea of what might have happened?
Try relogging, if that doesn't work, then your real ID was wiped.
I accidentally wiped my real ID once in the parental options in the bnet website, and when I made a ticket to try to get all my real ID friends, I got a reply that said there's nothing they could do about it and I would have to do it manually.
