I play online games just fine except the Arkham credits are not accumulating from the online match play. I have 587 and after each match the total goes up. I then leave the match to see the total back at 587. I have been able to purchase a bundle and earn credits. I do not want to do this anymore if I could. If anyone has run into this issue can they please inform me on how to fix the problem. This version is the PC.
