After doing a few Vex Incursions / Higher Difficulty Lost Sector runs I have not obtained the last remaining Exotic armor for my Hunter (Assassin’s Cowl) and my Titan (Phoenix Cradle). Upon finishing the run I acquire an Exotic I already own. When I view the Collection Page, both Exotics appear as I have not collected them. It is my understanding that by doing the two activities I am able to get new Exotics I don’t already own. Can someone confirm what’s going on or is it just extremely bad luck for me that I am not getting them?
