I have watched twice the ep 4 of Halo Nightfall and still not getting the rewards. What can I do? It has months since my first try 
MORE INFO: I have 6/8 rewards, I guess one of the missing is the tmcc’s wolf emblem. I have watched 3 times the whole episode both english and spanish and nothing has changed. I do have the eps 1,2,3 and 5 rewards. Just episode’s 4 are missing.
