How do you duplicate melee AI for customs?

[AdamArrighi]

I have been trying to change maps so that they have no heroes(can't build altars) and some other slight changes like seeing over trees and more peons can fit in mines. When I save it it says it is no longer a melee map because of said changes. The problem with this is that when the map loads the computers don't build. I assume this is because the normal melee AI is suspended and I haven't created a custom AI for them to draw from. My question is how do I duplicate the normal melee AI for a custom map? The one I'm working on is just Garden of War. It was supposed to be really simple but this AI problem is making it extremely complicated for me. Thanks for your help in advance.
