Kog'maw passive bugs interaction

when kog has exploded, a small area (his corpse) is unclickable, so lets say that you have slain the kog'maw, another champ appears and throws a spell at you, as the masterly champ you are, naturally you dodge this incoming attack by mere instinct, unfortunately your dodgeclick happened to be on the remainder of the little deathtrickster kog'maw wich nullifies your superior dodgeclick. i've also encountered minions that has become "untargetable" when standing over kog's blowned up body. so heads up! don't click the dead kog'maw, click beyond him! or else... (you will just continue in the previous direction)
