For a while now I've been having some issues when opening the end chest in dungeons such as LOMM and LoL, today I was running dread legion and it occurred twice in 3 runs. the issue is, I re-roll the rewards and the chest closes and I receive nothing. I cannot re open it or anything, I'm forced to leave without any rewards. This has occurred close to 10 times now across multiple dungeons/skirmishes and I can't do anything about it. Can someone help me or know how to fix this??
