hi chaotic bob
hope you dont mind but I made a minor mod to your security drone so that it dioes not send people to the void.
The trick is what kind of location you leave your drone in.
If its a simple location with an exit then the $actor's loc's loc will get us out to the outside of the location.
If you have a doorway in and out of a location (as you have) then the dron needs to know where the outside is - I hard-coded it in this case.
Thinking about it a bit more we should find the door, then use the door's link's loc to get us out to the linked doorways objects location.
Is that clear as mud?
Have fun now.
