you can't anymore, though you can make AI follow a certain route (if the map maker includes it in the map)
Curious to know why they keep removing improvements/features like this one. It was good fun getting a bunch of pidgeons attempt to climb the mountain while you sit at the top in a rover
they are improving it to work with the roads and everything, I wish they kept it in while they worked on it though.
Is there any reason they couldn't keep it while they worked on it? Some kind of incompatibility with the old AI code and the new AI code, maybe?
That's it. The old AI simply just checked where it was and where the target (whether chase or avoid) was and adjusted accordingly. Now it uses waypoints to stay on roads while doing roughly the same.
