I'm an Xbox 360 user. This glitch might have only happened to other users for this console. If you noticed any guns you had equiped or in your extra slots (not in your Vault) before the 2.0 update mysteriously having all the Upgrades available... Well why? All my Exotic and Legendaries suddenly had all the Upgrades Available. If you can explain this I'd love to know. I'm not upset that this happened... But it took the fun out of upgrading them... :(
