So i had a friend that just started playing destiny, and he saw that have a sword so he wanted to get one too. We got all of the missions done and then the worst happened he accidentally deleted the sword he had and from his cries and screams i could tell he was devastated lol. But i told him have no fear my brother you can get another sword from Lord Saxx , because once you you get it you can get again from him. So we did went and got him a mission and i noticed that my sword was at 297 but i didn't get the exotic sword mission, i looked and looked but no one had an answer for me. (despair) But like a i said you can get new sword from Lord Saxx right well if this happens to you just get another sword and bring it beyond level 280 and you should get the mission prompt once you enter the tower and you can complete the Dead Patrol Mission please check links attached to complete the Dead Patrol Mission.
