I had way over 10, some of them the 10 hour ones, of various dragon glyphs I played in many skirmishes and dungeons to get. The two in my overload slot had at least 6 hours left. I had a lot of my favorites the black dragon glyphs. Just a few minutes ago noticed every last one of them was gone. Looking at the item boxes there were about two and a half rows of them so that is like 24 or more gone. Please developers put them back.
