Despite being given the triumph, the emblem, and speaking to all the characters involved including Ikora and Zavala, I was not given any exotic rewards from Nimbus for completing the Legendary Lightfall campaign. There was never a point where it offered me anything. All missions say they are done, no red skulls to tell me I haven't done them. I've replayed the first mission on legendary just in case. I have even began working on the epilogue quests that reward a completely different exotic. Any help regarding this?
