I just finished tier 10 Delve “Earthcrawl Mines” and I got the reward and achievement. however, the request “Delves: Khaz Algar Research” doesn’t update the total number of Delves that I finished and it shows that I only finished 2/3 of the Delves. Yet, another request “A call to Delves” shows that I have finished 3/5 of the Delves this week, which shows correctly…
Meanwhile, the great vault rewards shows that I will get the tier 9 reward instead of tier 10 one.
