I mapped Verdant Brink to 100% completion on one of my toons a few days after launch and reported it in game since I didn’t receive the completion reward for it. However, I never received an email, as some players have, regarding this issue. Since then, I have gone out of my way to not complete any of the new zones out of fear of not receiving the rewards. My wife, SunyaGoda.8625, has had this issue with two of her toons after completing Tangled Depths and Verdant Brink.
Just wanted to add how much I LOVE HoT. Thank you for such an awesome expansion!
