I recently downloaded the Cold Storage and Legendary map packs for Halo 3, but after a few days I still have not seen them while playing Live with matchmaking. I have searched for solutions and have deleted and redownloaded the maps, loaded them in custom games first, and even deleted the system cache, but I still fail to see the maps online. I called Microsoft and they referred me here. Any help would be appreciated.
My playlist is Lone Wolves. I don't think that every one of the maps I downloaded happen to be unavailable for Slayer, but I would be disappointed if that turns out to be the case.
