- One of the solutions for this problem:

Create a new small cell (duplicate interior cell), this is important, make it small and put a XMarkerHeading in the middle, name it SafeXMarkerHeading, see picture:

Put 2 load doors in your interior cell and 2 load doors in your worldspace. Let's consider the front door the one that we can see the door texture, the other is the back door. Link your back door from the interior cell with the back door of your worldspace with teleport, don't flag the teleport marker of your front doors. Don't forget to put your teleport markers in front of the front door, final work should look like this:

Now you just have to put this script in the front door of your interior cell, no need to put it in the worldspace front door, just in the interior cell one, edit properties in the ck, DoorRef it's the interior cell back door (this is important, the script is inside the front door but DoorRef property is the back door), press auto-fill for the SafeXMarkerHeading if you name it right it should appear, see script and image:

Scriptname ACHDCVR_AH_PurgeExitScript extends ObjectReference  

;Script author Amethyst Deceiver

ObjectReference Property SafeXMarkerHeading  Auto
ObjectReference Property DoorRef  Auto

Event OnCellAttach()
	If (GetOpenState() == 1)
		GoToState("Busy")
		Activate(Self)
	EndIf
		GoToState("Idle")
EndEvent

State Idle
Event OnActivate(ObjectReference akActionRef)
  Actor Player = Game.GetPlayer()
	If (akActionRef == Player)
		GoToState("Busy")
		Utility.Wait(0.8)
		Player.MoveTo(SafeXMarkerHeading)
		DoorRef.Activate(Player)
  EndIf
EndEvent
EndState

State Busy
EndState

Don't forget to finalize navmesh in your interior cell and worldspace or else it won't work for the NPC's! Final should look something like this:

Done! Go test ingame! ^^

For other load doors you just have to repeat this process. There may be other solutions, check the forums for them!
