I picked up 3 exotic engrams from the Postmaster. Two dropped exotic armor pieces, the other one dropped the Unflinching Fusion Rifle Aim mod and nothing else. Is this normal? Because if not, I would like an exotic arms armor piece because it was a serious pain to grind those lost sectors just to get cheated out of the Exotic I was looking for.
Hey there. Yes it is sometimes possible for the mods and enhancement cores that drop from certain sources, to go to the postmaster as an exotic-like engram. This can happen when you decrypt a prime engram while your engram inventory is otherwise full, and can also happen when opening a Legend/Master Lost Sector chest, also while your engram inventory is full.
In any case where this happens, the reward was only ever the mod or the core, etc. You did not miss out on a genuine piece of exotic loot.
