Changing armor in the GECK

[Zexan]

I've been trying to add some different characters to the leveled character lists by modifying the premade NPCs from vanilla FNV. Where I am running into a problem is that any inventory changes I make to my new (modified) NPCs in the leveled lists don't seem to show up in game when the new NPCs spawn. I can change their hair or race or anything and it works fine, but no matter what I do to the inventory tab, they show up with whatever the vanilla NPC I started with originally had in their inventory tab. Anyone have any idea why this would be?
