Using setVectorDir on a static object, results in that object being visually rotated to the desired direction, but its Geo, Roadway, Fire Geo, etc LODs stay in their old place.

Firing at the object will result in bullets colliding at the old position
Aiming at the object will result in the adaptive crosshair following the visual outline but intersect with the old position
Walking at the object will result in colliding with geometry and walking on roadways in the old position.

setVectorDirAndUp and setVectorUp are also affected. {F27070}
