Thanks for reverting https://openstreetmap.org/changeset/151566709 , but it looks like the person who did that also changed the names in https://openstreetmap.org/changeset/150898937 .  Using https://map.atownsend.org.uk/maps/osm-deep-history/#/relation/13407035 I've tried to set the names back to the previous values to that https://www.openstreetmap.org/relation/13407035 is again "Morocco except Western Sahara".
