As the event of Doktor's Curse ends, I have not been able to complete the challenge Cursed Survivor and have been stuck on 4/5 matches completed. I have in fact won 7 matches. I have gone through a troubleshoot, rebooted the game, made sure the account was connected, etc. But it sitll will not check off my progress and now I will be missing out on the item pack and 850 battle points. Is there anything that can be done to rectify this?
