Corki Bug

Whenever I go up against a Corki, I am not sure how it happens but even though his gatling gun is not being used, the sound can still be heard. It will stay that way throughout the entire round, even over his body when he has been defeated. I am not sure if this has happened with anyone else, but it has been going on for a while now. After the first time, I thought it would go away, but after the third or fourth time, it is still there.
