I know how
I have to open this door. My problem is how to make WPs for bots, to force
THEM to open this door from outside...I don't know if I have put there near this door the use_button flag.
This new dll I'll try to test morning (now in my country it's 2:32 AM and I have to go to sleep - I'm tired...

)
Look once again at light switch-buttons (these switch need to be "used" - but bots after using them get stuck...).
Do You have a map cs_house? There are many switches for light...
