[SOUND / AUDIO] Corki'sGatling Gun ability sound effect persist indefinetly

The sound effect which accompanies Corki's Gatling Gun ability (the sound of machine gun fire) is supposed to stop when his ability stops. However, if I'm on the team which Corki is fighting against and he goes out of vision while his Gatling ability is active then comes back I hear unending machine gun fire whenever I'm near corki for the remainder of the match even when his ability is not active.
