Looted NPC or lootless NPC

What is this suggestion related to (eg. Website / Launcher / The game itself / etc. ): Game

Make already looted NPC and NPC that died and have no loot in it non-lootable but targetable. There is no reason to open loot window of empty NPC corpses. At this moment empty corpses lie until they disappear. This is a problem because the “loot all items” feature(one that binds to the Keyboard key) does not work properly if there are bunch of corpses in small area. Trying to loot using this feature ends up with looting the same empty corpse over and over. So the player need somehow to change its own location to be able to loot other corpses. But if empty corpse is un-lootable than the looting feature should works perfectly.
