So today I swapped out an armory that had 1 item (helm) that was missing. I knew the helm was missing as I had salvaged it previously, but I had a different helm in my stash I planned to replace it with. Well after equipping the armory, I went looking through my stash tabs, all my other UE gear was missing, including the helm I was looking for. It’s as if my stash got rolled back to some previous point in time and took away all UE gear. Then I logged out of Diablo and back in, then viola everything was back in my stash. Very strange bug.
