I've been trying to get trough this queststep, where I Have to decrypt 5 legendary engrams, 1 exotic engrams and kill Fallen on Nessus with Drang. My problem is that the game does not give me any "decryptable" exotic engrams at all! All my exotic drops that I get automatically auto-decrypts themselves. No need for Rahuul to decrypt them = no queststep completion. I tried not to pick up engrams, picking directly from chests, XUR, EVERYTHING! The engram on the pic I linked is a random engram I did not see dropped. It's describtion says that "A cryptarch would be thrilled to decode this to revail its true nature." yet when I collectit from the postmaster its automatically decoded! No chance to show it to Rahuul! I dont want more exotic engrams, I want my quest step to be completed and to get my Sturm handcannon! Thank you bungie.
