Akthi and Anundr No Reward

Bug Report ID: #2276264292

I've just killed Akthi and Anundr, then reset the zone with a Ctrl+Click and did it again. Both times the boss did not offer a reward, nor clear the quest from my map. I am currently unable to complete this quest.

However, the Challenge for this league DID mark them as defeated, and shows both with a green check.

EDIT: Third time's the charm! Got my reward now at least!
