Rewards from my faction and cryptarch always show purple in the postmasters inventory, but are ALWAYS blue when opened. It's the exacts same problem as before. The RNG is weak as hell now so I have to bust my balls levelling up, just to be shat on! If you can fix it with the engrams you can fix the rewards! If my next reward shows purple but opens as blue, at least I will have nice shiny Destiny coaster.
