The Nightfall triumph for this week is bugged. See link for details. In fact I also got the 100,000 nightfall score in another lobby and while I got the pinnacle for it didn't fulfill the triumph. When is bungie going to fix all of the bugs in this game. It is getting more and more frustrating as seasons progress. What you all need to do is temporarily shut down new content production and concentrate on fixing all of the bugs. Just a suggestion.
