Golden Key Lost Loot

I used my golden key but didn’t save after I used it and the next time I logged on the weapon I got was gone. Same thing happened with the Hyperion assault rifle in the mission for Zed

need to save or pass a save spot or stuff disappears, to make sure your gear is saved before guitting, go into menu to BAR Stats, turn this off then back on, this forces a save and any gear you’ve picked up to that point will be saved.
