I got the Limited Edition for Halo 4 and with it you get all 8 Specializations, so I put in the code and now they just went away. So I downloaded the New DLC and they came back, but then one day later they were gone. It realty annoying because I'm about to hit SR 50 and I only have 2/8 Specializations locked. How do I get all 8 back?????
