I've never had this problem before, but i'm now running into an issue where i take an engram to the cryptarch and occasionally he doesn't give me anything after decrypting it. Its only happened twice out of about 15 engrams i've taken to him so far on my new character, and only to weapon engrams. I don't know if its effecting armor engrams yet. The engrams i gave him were a primary weapon engram and a special weapon engram. Is anybody else having this issue, and does anybody know a fix?
