AI Goals/Pathing

Socite

Is there anybody who knows how to set up some form of goals or patching for the AI in the World Builder? It has to be possible some how since AI works fine on official maps, whereas on seemingly every community map the AI largely focuses the main objective after the first few minutes. On the map I'm currently working on, the teams start on neighbouring sides of the map and AI completely ignores anywhere below the top half of the map... I'd hate for it to become a purely PvP map, since a lot of people like to comp stop plus it would help me playtest the map.
