Halo 4 Campaign Master Chief Armor

I completed the campaign on legendary and i heard that i was supposed to get all the master chief armor and when i completed it my partner got the armor and i didn’t. is there something i did wrong? on my service record it said that it was completed.

check your commendations and see which ones aren’t “completed”

yes it’s bugged and you will have to redo them levels

yes i just finished it on legendary as well and it says on my service recored i did all of them but on the game it says one level istnt done so check the game and redo the level its what i had to do

NOT service record, commendation list…

One person that had the same problem wnr back and looked at her missions and saw that she hadnt watched the prolouge on legendary…
As soon as she did that, it gave her the armor.
