I’ve have tried with my friends getting all the Halo 4 DLC achievemnts but some of them won’t even pop up after we have done the requirements like 500 times. This problem happens to me on on the Crimson, Castle and MAjestic map packs. Is 343 doing something about it and trying to implement permanent ficxes or should we just give up? --__–
