So i used the send to xbox on this site to send maps to my xbox. now the problem is halo 4 keeps downloading them to my xbox repeatedly after each game. spamming my maps/gametypes with said downloaded maps. could anyone tell me the way to disable this?
There is no known fix, but you certainly aren’t the only one with the issue 
If you plan on playing offline gamemodes like Forge, Campaign, etc then disconnect your Xbox from Xbox LIVE and it will stop the constant downloads.
Other than that, you’ll have to wait until the issue is fixed by 343i.
