Today I completed a successful Dalaran Heist run and did not receive credit. Here are the details:
Adventure: Dalaran Heist
Purchased with: Gold
Format: Normal
Chapter: 3 Streets of Dalaran
Hero: Warrior Mr. Chu
Hero Power: Invigorating Brew
Starting Deck: Random Deck
I beat all 8 bosses, and was very disappointed to see that I did not receive the Star for Mr. Chu, or the Check Marks for the Hero Power and Starting Deck.
