Forge maps not saving

I started making three forge maps today, one on h2a forge, and two on halo 4 forge, after saving, and naming them all, they all failed to show up as available maps anywhere. I’ve searched for a solution, and nothing appears to be working. Help?

Also, on a side note, is 343 still supporting mcc? I haven’t heard much from it since halo 5. And the game still has plenty of bugs and glitches they are very capable of taking care of.
