(Sven coop) Bots don't push buttons, Did I miss the button thing? Options

[Emmanuel]

As you know, sven coop is known for having some maps that require at least 2 people to push 2 buttons at once to procceed on the map. But the bots don't do this.
I tried adding a waypoint just in front of the button, first with nothing, then with stay close to, and i tried then with lift button, pusheable, scientist and barney options.
None seem to work and the bots don't push the button. I waited half an hour or 20 minutes to see if only one would push it, none of them did.
Am I doing something wrong here, or it's just some maps?

[random]

i once waypointed some maps(badly) but mine seemed to push buttons sometimes without me waypointing it so not sure what the problems is.
On incoming the bots never turn the values they go straight for the grate and drown or die a different way.
which map are you waypointing?
