The navmesh door link in the Thalmor Headquarters in Solitude (SolitudeJusticiarsHeadquarters) does not match the door triangle number referenced by the door itself (set to triangle 73 on the navmesh and triangle 9 on the door). I suspect Open Cities may have moved the teleport marker slightly, so it ends up on top of a different triangle, and that the navmesh update has accidentally been cleaned out in xEdit.
