I have problems with the DLC achievements in Halo 4
The only problem I had with the Halo 4 achievements was for the Crimson DLC, all I did was uninstall the DLC and then reinstall, and cleared my cache on my storage device (360) and then I managed to get the achievements. I am not sure which system you are currently on, is it the One or 360? if it is the 360 my best advice would be as I said. It worked fine for me. If not, I would check back on this thread incase someone else has a solution for you.
