About that light at the top - You are afraid the most - maybe it's not clearly describen in ny docs, but if there is some place You don't wish to go by bots, just... don't waypoint that area so they will no go there... It's like humans do - if they will have the only choice to die (because of falling down), they will not go there. The rest You can see on my pictures. The doors with buttons - here You have the example how to waypoint the door with buttons - example from de_rats (similar map) - no button flag - bot will find the button if he needs, if the waypoint placed in front of the door "can see" the button. About that kitchen-cabinet You were afraid - there is a ladder - they can go...

Now - I think - You can waypoint that map, but I'm pretty sure the map has some problems with spawn points (they are too much close to each other).
