Ok, I'm trying to figure out how leveled items work on non-respawning NPCs. I ran into this when swapping out preset clothing for leveled list based clothing. It only works on either a brand new game or for a mod-added NPC, a clean save and reloading of the mod.

When, if ever, do leveled items on NPCs update?

I seem to remember a discussion here about how some leveled items are generated on initial game load, specifically involving Vile Lair? And it also affects NPCs...somehow?

I've googled around, without much luck.
