Lift button, well.. Options

[[ASA]ODEN]

I try to make waypoints and paths through the Marines first lift on ns_hera (but question is generic )

Situation:
I start with a normal WP (Blue) and a LiftButton WP (Red) in front of the lift button (x) from which I put a one-way path to a Wait-For-Lift WP (White) on the elevator.

Impressive graphics:
B---R-x------W

Result:
Still, bots don't push the button - merely waits specified 10 secs and jumps out getting hurt (poor bot )

Q: How is the "red" WP supposed to be used?

(Tried with normal blue and seen bot push the button once or twice (out of hundreds of tests , this since bots push the door button at a blue waypoints)

regards

does the lift waypoint have to be a bit away from the lift, because i noticed on one of the standard ns maps, that ALL well, 99% of the rcbot aliens got stuck under a lift (which was vital to that part of the map), im just wondering, because i tend to waypoint maps with very minimal ladders and lifts because i do not know how to waypoint them properly
