So I am trying to figure out whether this is by design, or am I missing some trick cause I am newbie. Say I need to stock up on leather. If I go and hunt small animals (moles, squirrels, rabbits), I can put quite a lot of corpses of those dead critters into my backpack, which will result in reasonable loot of skin/fur (plus meat, bones etc). If I go hunt some bigger animals, like fox or badger, I can't put those into my backpack, I have to flay them on the spot and then basically discard all the byproducts apart from the skin. So as far as I can see it, if you discard byproducts of big animals hunt you get just as much skin as when hunting small animals. But with small animals you also get byproducts - hence hunting small ones is more efficient.
Is there some flaw in my logic? Cause it seems like the bigger the risk (hunting bigger animals) the bigger the reward should be, which is not the case here.
