Resetting TVHM reset bank, lost 100+ level 60 annotated legendaries

I reset my quest progress after I noticed I sold my pearl artifact. I wanted to get it back, so I reset the missions as it was the only way to get it (to my understanding). I just noticed after looking in my bank for a gun, that I only had 31 level 50 items, when I had just cleaned and organized it out. Lost a bunch of amazing annotated grenade mods. Like this is a MASSIVE bug.
