Game crashed just as I was given tree of whispers cache, which I never got and now Tree of Whispers shows I have a reward waiting to claim, but no reward at tree. Tried checking all difficulty levels, no reward but shows available at every level. Tried logging out and back in. Tried logging out of BattleNet and back in, still no reward.
This crash has occurred multiple times since season 6 began, never an issue during 5 prior seasons.
