Problem: I have tried each AI for the two computer enemies in my campaign mission, but all they ever do is harvest

Info:
This is a campaign map featuring a modified version of Protoss and regular Terrans as enemies. They start on a highground island at the bottom-right of the map. All lowground to the north of the Island depletes shields and energy.
The Terran have one firebat hero, and the Protoss have a few air heroes
I've tried changing the location of the AI trigger, but it just makes the Terrans act like a commitee of idiots without changing the Protoss at al

Should any of this even affect the AI's ability to build or attack?
I need help please.

Make sure your player's race, the units and the ai action are the same race.

You also probably have to give them the buildings they have in the campaign, as the campaign scripts are tailored for the respective levels and they might assume certain buildings to exist.
