Created attachment 44 [details] The door, from the non-visible side. When you place the non-damaged version of the double-door furniture object, it will only be visible from one side of the wall that it is placed on. When you go through the door, it will look as if there is no door there, but the door still functions if you walk to where it should be. On the attached screenshot, there is a double door right in front of the player, where the mouse cursor is, but it is only actually visible when outside the room.
