Upgrade progress lost on The Ram helmet. I had the first two perks completed and filled in. I had the last perk's circle closed, but needed a little bit more glimmer. I went to the Dark Beyond for some glimmer farming. When I knew that I had enough glimmer, I went to complete the upgrade, but the circle was only half closed whereas it was completed before. So I continued, hoping to just grind it back up while glimmer farming. But then I checked again and the last perk circle was not even half closed. It reser to nothing. I had lost all of the progress in closing that last circle.
