Explosion 101

OK, slo I've ran this Co-Op mission a few times and every time I complete it, the associated achievement/trophy doesn't get awarded to me, or a friend who I've ran this mission with.

Will this be fixed?

well the Challenge is given to me, I play on the 360 and there is an achievement associated with it.
