After loading any of my saved games and playing along, I usually find a missing mesh on an enemy (usually a set of arrows).
I've tried both Refscope and Form ID Finder and I haven't had much luck.
RefScope gives this as a result:
Ammo FF083F62
Defined in a player saved game
(Is a cloned form)
Missing resources:
(No icon defined!)
I can tell it s a set of arrows because when I pick it up and equip the item, it makes that equip arrow sound.
I've even tried to go to Wrye Bash and try that "Repair savegame" option.
Thanks in advance.
