So when the Taken King dropped, the ThunderLord was not in my Exotic Weapon BluePrint kiosk. It says i have it in my Grimoire but it still says "Requires Discovery" I have it in my vault as well as Necrocasm (which is not showing on my Grimoire) that is also in my vault but i cannot take it out. I'd much like to have my Thunderlord back because it's an awesome gun and i know i had it because it was my very first exotic weapon. I hope Bungie reads this and can help me resolve this issue over missing Items. -CruentaDiabolus
