I just completed the last mission for legendary campaign and after the cutscene I got kicked before I could get the exotic on my Warlock. I managed to log back in and noticed the checkpoint was still there so I beat Calus again and still nothing. I checked again and the checkpoint is gone. I know I didn't miss a chest in a previous mission because I replayed every mission on Legendary because I had missed a few. Is there anyway to fix this? I will rerun the final mission again if needed. Edit: Nevermind, I just logged back in checked we Nimbus. His icon wasn't glowing but I got the stuff.
