I've been playing around with http://www.gamesas.com/index.php?/topic/1141563-relz-the-strip-open-modders-resource-version/, trying to repopulate it and now that I've gotten around to just setting the quest NPCs (Billy Knight for instance) they stay active and run the AI fine but ... they are naked. They have their correct inventory, they just spawn with nothing equipped, and don't equip anything.

I've been diggin so much into how the scenes move NPCs around, show random events like the securitrons covering spray paint, control securitrons changing to mark 2, and spawn drunk NCR npcs like the women in the fountain scene that I suddenly feel so lost on something that seems like it is probably really, really simple.

How the heck do I make these specific unique npcs equip their damn clothing. Obviously I am frustrated.

Try waiting four'ish days alone in an empty interior that their inventories will reset?

This is not the only place this happens.
I saw a naked BoS paladin inside their bunker the other day.
