map issue

Does the game no longer recognize unpacked folders? Or is there another issue? I went to add a few assets from one map to another and the game no longer has the map I unpacked as an option. I even tried compressing it but still nothing. I moved it and put the original zip file and it works fine. I literally added a couple buildings to the map but it will not load. I tried unzipping the og file right to the same folder and it doesnt work. Any ideas?
