Sooooo... I've spent the better part of a week grinding away to get ten Archive Cards, so that I could get x5 XP for 50 Matches. Finally did it, "bought" the bonus, had a few matches... then turned off the console. When I went back to it later, I was back to regular, x1 XP. Down the toilet. Is that a glitch or supposed to happen? MUST you have fifty consecutive matches?
