Nexus Turret Noises

Ok, so I had this bug a month ago. Just forgot to mention it on the boards though.

Basically this bug plays a sound which sounds like the turret lasers, except it has more of a static sound to it. It was like the already alarming laser turret sound + more of the sound like a metal ruler being scratched on the ground + with a buzz.

The opposing team was bashing our two left inhibs and some were just killing us under our nexus turrets. I think I noticed this sound after they killed me instantly under the nexus turrets, and then we cleared out under the turrets and the turrets weren't targeting anything I could still hear the sound. It was louder than the actual turret sound, and also got quieter as I moved away from the nexus turrets(that's why I think the nexus turrets were the problem). I didn't play on the SR after that but I think it could've happened to other people as well.
