I already watch all the -Yoinking!- episodes on halo channel, i think its a bug
I have almost all legendarys excepto the nightfall because of that and that is so unfair
(English for bad sorry)
It might have just glitched
You could try again fast forwarding the entire thing.
Check the customization menu. It should be there. It may take a while to show up on your req inventory menu… eek.
i have the same problem.
maybe you need to watch the second stories?
or maybe it’s just my internet playing tricks on me(as always)
Change your languages on the media your watching nightfall to english , it should unlock the stuff , it did to me but as far , its only h:mcc stuff …
