1. Load up the reproduction mission.
2. Call radio alpha (0-0-1) to make AI units run through the several mazes and the tight doorway.
3. Watch as the AI unit in a sparse non physics object maze is able to clear the maze effortlessly while the AI units in the car maze, the partly physics object blocked identical maze and the tight doorway mazes all get stuck. The result is especially sad for the tight doorway guy because just a single step forward through the 2~ meter wide gap would free him from his invisible pathfinding prison.
