Fortress walls screw up AI waypoints

[kelgram 10]

The fortress walls in ArmA 3 which are represented by grey rectangles in the editor map seem to completely screw up AI waypoints.

I am wanting a Officer to escape to a helicopter that is sitting on a wall in the Kavala fortress (south west Altis).

However as you can see from the screenshot, he will stop outside the area of the wall.

Any ideas how to solve this?

Only thing i can think of is name the copter heli and on final waypoint near the heli put this on the activation this moveInDriver heli

I suppose you can try to force move animation on AI and make it run to the helicopter. I tried it, and that wall is hit and miss if you are just a little bit off, AI runs inside the wall.
