I don't know how many people have had this problem, but this one ails me constantly. It seems that every couple of days when I open the arena after getting a new card, my Arena completely resets. I get the intro messages pointing everything out, my previous deck is gone, my electrum is all gone, and any match results are gone as well. It's not a big problem, but it is annoying. It might be related to different computers as I just loaded it up on this computer for the first time and it reset. But I have noticed it happen on the same computer, only after a longer amount of time, around a week or two at the max.
Anyone, help?
