CertainDistress my bad, I assumed you meant for Zombies instead of Multiplayer. Anyway, the DLCs tab image you’ve provided is not showing the Apocalypse map pack, and the zone\all image is showing that the number of total files corresponds to the number without the Apocalypse files. Are you facing the error on maps other than Dig, Frost, Pod, and Takeoff? If not, then the reason you’re facing the error on only those maps is because you don’t have the maps from Apocalypse installed. If you’re facing the error on other maps, could you provide a full list of the maps you’re facing the error on, and also provide a screenshot of the external terminal window while it’s in fullscreen and while making sure the PLATFORM_MISSINGMAP line is at the very bottom?
