Important caveat: Even after you transform the gate, if you continue to hit the hotkey, it will continue to waste 50 wood on the already converted gate!! It also converts single pillars into gates. So your wall selection skills need to be sharp
Asian civs don't have the cWallGate tech enable hence why the AI can't make gates as Japan, China or India. I wonder if that ui command is affected by the same oversight by BigHugeGames?
I tried to use chat commands to give the Asian AI gates but it was a waste of time.
