I think I may have been hit with a day-ruining bug. I finished forging my first pulse rifle frame and couldn't pick it up because my inventory was full, but my eyes lit up when I saw the display icon for it had the masterwork border design/shimmer (!!). The engram itself had a unique shimmer as well. I got really excited and scrambled to dismantle the random blue clogging up my inventory, still standing on the forge engram, yet the moment I exited the character menu, I received a normal random roll Blast Furnace. Wait what. Did I just get screwed out of a fully masterworked, curated forge weapon because of some wonky inventory bug??
