When the bot looks at a very near waypoint, approaching it, it does it either standing up - the look gradually lowers to the ground, because the waypoint origin is lower, compared to the eye/camera origin. Or it approaches it crouched, and the look goes up, because, now, the waypoint origin is higher compared to the eye origin. This is why, sometimes, the bot's look seems to follow an arched line across the sky, the bot just passed below the waypoint origin, or it moved in very close proximity to it. I don't have hard facts, I've come to this conclusions after watching a lonely bot navigate the map on its own, with visible waypoints turned on.

But this is not the only remaining issue.
