I have been running Nightfall Strikes for the past couple days. I have accumulated 100% of the points needed to complete the quest, have been alive when the bosses have been defeated, and have gotten the final shot (I believe) once. The "beat Bosses" portion of the quest is not showing any progress (like 1/3, or 33%, etc) and is not showing that it is completed either. I've scrolled through several pages of forums but the only thing I've found referring to this problem, anywhere, is a post on Reddit, where I am not the only one experiencing this issue.
