What *should* happen is that the pet should behave as if the owner hid or became invisible. That is, the pet should suicide if summomed, or should uncharm if charmed.
Our inclination is that we should fix this bug, because the tactic is pretty lame and allows the necromancer to do things they shouldn't be able to do, such as soloing high level critters in closed quarters.
So, should we change this? Or leave it as is?
