Couldn't tell you other than a guess that the coding for a 'set' npc is likely at least slightly different from that for PC characters (which are always changing 'skins' with armor, leveling and ungrades).

I've never felt so short before, though...lol. I know lore does state the nelfs are bigger, but...yeah, that's a LOT bigger than I figured they were. Too bad I can't get a player nelf to stand still for a shot like this. :)
