Note to Coop players: Like Sandbox+, if you join somebody else's coop game, the elevators will not work. This is because the "sr3_city.lua" script does not run if you are not the host. However, if somebody joins YOUR coop game (if you are the host), the elevators will work for you (only). I may add the ability for coop players to follow you through the elevator if I can figure out how to test it. But, again, it will only work if you are the host, and they will not be able to use the elevators on their own.
