Non- skinnable animals

[Force_of_Will_]

I was in the area near Hempstead that has the Bugbears,dire badgers,dire boars,worgs and lions.
After killing these animals I attempted to skin them. I found I could search the animal bodies for treasure but couldnt skin them.

Working as intended, consider them super famined animals, useless for crafting, it is the dark ages after all.
