So I went through the whole raid until the last boss, obviously collecting the millions of useless green and (semi-useless) blue engrams that drop now. However, I also had a few legendaries and exotics drop. Problem is, there were so many green & blue drops that they overfilled the postmaster and therefore deleted 4-7 legendaries, and would have deleted my exotic engram had I not made a point to pick it up before leaving. TLDR; There needs to be a way to prevent blues and greens from deleting/pushing out legendaries and exotics in the postmaster! Edit: Thanks for the likes guys & gals, this should be a simple fix but it would [b]really[/b] help!
