I play MCC Halo 4 forge and have spent plenty hours on a map. It is done now and Halo Waypoint can’t see my creation. I am Rikermon and my map is Tuxedo 4.1 and anyone can enjoy it. But I can’t see a URL location on this site that I can post to forgehub so others can download it.
Downloads are done in-game by going from the main menu to Roster > Clicking on your name > Find Player > Search for player > File Share.
I followed these steps and accessed your profile in game and was able to download your map.
