I have a friend who is on the last step wherein he must complete the Nightfall with 5+ minutes left on the clock. Me and our 3rd man both already have Rat King so we've been trying to help him out. Twice in a row, we've completed this week's Nightfall with well over 5 Minutes remaining, and the quest step has not progressed. I have confirmed he's on the right quest step. The only possibility I can think of is that he HAS to do it with other people who have the quest as well? Is this the case? Are we missing something? Or is this just a bug? Thanks in advance. ((Edit: I'm playing on my secondary character who has not gotten the RK quest nor completed it. But I have the Rat King in my inventory which I transferred from my main))
