Turret sound won't stop after dying to it

Just played a custom on PBE as garen. I died to bottom lane red side inhibitor tower (not a champ) while just having some fun. After it killed me I noticed the noise of the laser hitting me wouldn't stop unless I got out of vision of it. Even when I was dead, I could put my camera view over that tower and would still hear the annoying buzzing sound. Don't know if this is a garen specific problem, or just with that turret. I'll keep "testing" this bug on pbe. :3
