You have to start all the way from the start of the level. The game know that you started from the rally point which makes it like cheat to start from there. If this does not work I suggest you call Microsoft to get the problem fixed.

one problem maybe is you have to start on arrival. if that doesnt work, make sure your not standing on it. if your not then maybe your in the wrong place. remember its to the east of where that huge phantom is that drops all of those brutes and grunts. its on a huge boulder if you keep going to the right.

You have to play it on legendary.

That's what I did.

Make sure you start from the beginning, not a rally point.
