Hi. I just completed the Lightfall story under legendary mode, which should provide me an option to select one exotic from two. However, I received an exotic engram instead. I wonder if this is a bug, or I accidently missed any of the legendary mission. If I did miss any, is the random exotic part of the reward? plus, any clues in the game except manually running all quests again to check which is missed. If I did not miss any, do I get the bug fixed and be able to select the exotic armor?
