So I was playing and helping a friend of mine level up when we reached the moment where we have to go watch the Reef cutscene. So I split off to do crucible and noticed that not one but two of my exotics were gone. My newly obtained from a Legendary Engram Gjallarhorn and my fully upgraded Starfire Protocol from a Nightfall. Upon 10 minutes of frantic searching, Starfire magically appeared in my inventory. But now 30 minutes later my Gjallarhorn has not returned. Please help? Or replace? I've been grinding for Gjallarhorn everyday and now when I finally get it, it glitches out of my inventory. Have Grimore cards to prove having own said exotics. Gamertag: RaiTheLight System: Xbox One
