A previously long-since killed uruk's body is lying in the "Sauron's Army" menu, and has been there for a while. Never moving or going away. I know that this means (since his head isn't on a pike) that he should be coming back, but he's not. He hasn't popped in while I'm running around, doing a mission, or even when I've been hit to near death on my knee (sometimes they appear when you're about to die).
So, anybody have a clue?
(Funnily enough, this Uruk has the title of Shaman, although this is now my second case of this happening.)
