I have a friend with this issue, and knowing the problem is keeping us from wanting to clear any new content, we’ve been wanting to hit the expansion content for a while now and this situation only worsens the wait and drains on the will. Please fix this issue quickly, I would like to go on playing the game without fear of missing out on rewards, and overall feel comfortable playing a game I enjoy.
Edit: This happened upon completing Cursed Shore, not any of the new maps. Thought this to be relevant so the entire game zones are looked at and not just the expansion content.
