This Morning roughly at 4:30AM on 31JUL15, I applied Etheric Light to my Felwinter's Lie, bringing it up to 365. I then proceeded into an Iron Banner match, and attempted to equip the weapon ingame. At this time I noticed it was not in my inventory. I verified with the Destiny app that the shotgun was not in my Vault or somehow transferred to another character. I did have the weapon locked to prevent accidental Deleting as well. The gun (Along with the etheric light I applied to it) is simply gone. Could you please research as to what happened, and as to what the correction for this issue is?
