Thank you ! Thank you ! Bengal ! Finally I can publish my maps ! :D
I owe you. :)

Oh - forgot to mention - if your capture zone is too close to 2 key buildings (if they are bunched up) - it might not work very well - so try moving the capture zone aroud.

Hi TiGer - Once you have a Key Building on your map, you need to put a "Capture Zone" on top / touching it - the buildings will not work without them. Once you have key buildings and capture zones in your map, you need to find the "map_info" file in the map directory. open that file in notepad, and make line that says <has_key_buildings>true</has_key_buildings>. The default is false. That should solve the issue. Remember that once you set key buildings on, you can no longer play the map in the Custome Battle area, but have to go host a game in the multiplayer battle list.
