Kog'Maw explosion on an infinite loop

While playing a custom game I encountered an odd bug related to Kog'Maw's death. I had just slain Kog'maw, got just beyond visual range of his reanimated body, and went through some bushes to base. When I got back to lane, each time I saw Kog'Maw it would start playing the sound leading to his explosion. It was only while I had vision with my character that the sounds would be heard. It just seemed to loop on and on. I'm not sure about recreating the occurance, but I wanted to at least make it known. I feel sorry for the poor guy stuck with these sounds his entire match.
