Next update we should be able to build and repair this doors, probably the coolest looking ones in the game, i claimed a Dvergr building in the Mistlands but could not repair the door/ place a new one, there is no logical reason for this, i know admins can spawn the door with the command spawn piece_dvergr_wood_door but in our server we have a "zero admin commands" policy so it won't happen, i really hope we can build this doors and the other Dvergr stuff in the next update ...
