I have ran the dust palace over 10 times today with different groups and not one person has received a flayer mantle or treads upon stars. Also the loot which should be dropping as engrams directly on the ground post kill are simply appearing as on screen rewards. I am seeing many other posts on which the same issue is being described. I have been waiting a long time for this nightfall to farm the cloaks and would really like for this to get fixed.... I hope to hear something from a mod or Bungie official. Thanks...
