Melee Computer team question(s)

I would like to use the Goblin shipyard for islands on the map. Running the game the computer was on an island and never used the ship yard for troop transport. Using shallow water computer just waded across, using deep water computer stopped at the edge of shallow water at deep water.

Am I to assume that things like the ships and zepplins can not be used by the computer? Running it again with myself on that island I was able to purchase and use the tree ships so its not a path problem to get to the shipyard.

Also, will the computer attack destructables like city gates to get to enemies?

You must use triggers and order the computer to do those things.
