Hello
I am requesting to add the elevator support to copy /paste.
Everytime a base is pasted wih elevators in it, causes issue where if a players enters the elevator, disconnects and cannot log back in to the server because the body is laying inside the elevator. So I have to move them somewhere outside for them to login back to server.

The workaround is that remove the elevators while in noclip mode and place new ones in manually.

The error thrown upon entering pasted elevators is as follows,

Exception (cs:60597): NullReferenceException: Object reference not set to an instance of an object. ElevatorLift.Menu_LowerElevator_ShowIf (BasePlayer p) (at <00000000000000000000000000000000>:0) ElevatorLift.get_HasMenuOptions () (at <00000000000000000000000000000000>:0) BasePlayer.UpdateLookingAt (System.Single radius, System.Boolean includeSecondaryEntities) (at <00000000000000000000000000000000>:0) BasePlayer.ClientUpdateLocalPlayer () (at <00000000000000000000000000000000>:0) BasePlayer.ClientCycle (System.Single deltaTime) (at <00000000000000000000000000000000>:0) Client.Update () (at <00000000000000000000000000000000>:0)​

Dude said in another post that he's working on a complete overhaul which will include elevator support.

Right now I just replace elevators and rewire. Your red buttons can stay and it's best to delete the elevators before final copy in a wipe, or you'll need to use "ent kill". 
Picking up the bottom one gets rid of all except the top one.

LOL, I have buttons at every floor and 3 elevator shafts to get to the top. It really is a pain in the A.
