Unlike every other type of corpse, bandit corpses don't displace the grass around them, making them very difficult to find after dispatching of an entire spread out group. This makes looting bandits much more annoying than hunting animals, and just seems plain weird when everything else squashes the grass down.
If this is intentional to add difficulty, I suggest giving the bandits a few types of "camo" (probably just green clothing) rather than having the grass clip through them.
