Bungie, when trying to complete the Historian milestone for Age of Triumph I was not able to get the last ghost shell. I look it up and its on a exclusive Play Station map. My main issue is my friend like me on Xbox One got the ghost shells even though I didn't as we we're doing it together. It seems that he got the extra shell right from the start as I did not. Please fix this issue so all Guardians in Xbox One have the chance to finish the crucible section.
