I played on my cousin’s Xbox and downloaded my profile so I could play on his Xbox. I unlocked some armor from ranking up and now it isn’t there on my Xbox. Do you think it could be because of missing DLC? Or something else? It also said I unlocked the scanner helmet, but I do not see it anywhere please help!
Same problem 
You probably pressed “Harddrive” as your saving divice on your friend’s Xbox. so if you download your profile again to your friend’s Xbox, you’ll have the armor
