Chromatophore: When looting a body, instead of the highlighted item, I pick up something else. So for example if the loot list is ammo, weapon, food in that order and I want the weapon, I highlight it and press 'e'. I pick up the food. It's infuriating.
Am I doing something wrong or is it a known problem with the loot system? I can find plenty of complaints googling about loot that cannot be collected because it has partly clipped out of the world, but nothing about this specific issue.

xXpert: I'm having this same issue, even after the 2.0 update, have you found any solutions to this yet?

ramzesIII97: The "E" key is also "going down" key in looting menu by default. When you press "E" to loot, your selection goes down 1 item and you pick the second item in looting menu. Solution - change key binding for "going down" in "Interface" section.
