The lotter button on the bodies of the monsters, as well as the F key and the pets do not lotter certain items of the monsters, for example, the long sword of the galiantors does not lotter it in any of the ways and I do not have it deactivated, someone else happens with it other monsters?

pet dont loot long sword

I just got that same problem with a heraldic targe (epic) from a dead boulder thrower (elite) : pet didn't loot, autoloot key closed body without looting item. I had to take item manually. I didn't think about trying MAJ+right click.
