Land pathfinding issues

Hi,

I am trying to make the vanilla AI pathfinding behave according to its set altitude requirements, in a land vehicle. The issue is that terrain height seems to be ignored, no matter what settings I use or which behaviour/movement combination is selected. When I display pathfinding using the tool, I notice that waypoints are actually placed below ground level.

Another issue I have found, is that after some point, units seem to get stuck in "Moved xxx east and xxx north to... find land of height xx".

Screenshots attached for both issues.

The vehicle I use is a very basic tracked chassis with an AI that has a configured yaw PID. It should not matter as this is the case for every land vehicle that I've tried. Blueprint attached for good measure.

Screen 2: stuck in a loop pt1
Screenshot 3: stuck in a loop pt2 - this is the other tooltip that the game flickers back and forth to from the previous screenshot.

Screenshot 4: example of a waypoint placed above the water
