I have done this week's Nightfall 25+ times. I've tried every difficulty except for the lowest and in all attempts, there has been a missing champion. I have killed every champ that spawns in and never once got platinum because one of the champions does not spawn. As far as I know, it's the overload hobgoblin in the room after the 2 ogre room. The reason I have an issue with this is obviously because of the difference in the rewards. supposedly "common" drop rates of nightfall weapons and yet I have not gotten a single Palindrome or even Swarm. One of my friends got palindrome second try one got swarm around his 10th (proving they do still drop). Please Please Please fix this Bungie or add the same guns as rewards next week because I have been waiting for palindrome just for the strike to be bugged and "common" rewards to not be common at all.
