This is the second time this has happened. Both the level 21 and 34 were supposed to reward me with 2 Aetherdrift Mythic Rewards. Both times however, it has not given me those rewards. The first time I thought maybe I just missed it. Same thing happened this time, game rewarded with coins and experience but no cards. My mastery shows that I have been awarded that level, but in reality I received nothing. Please address this issue.
