[JP Server]Certain champ alternate skin sounds not properly playing on ability cast

Hello Rito Gaems, I'm GigaBreaker88. A friend managed to give me a beta key to the JP server, and I took Yasuo into a custom game with the High Noon skin for the hell of it. I noticed right away my Q used the default skin sound, without the noticable "bang" it's supposed to. Interestingly, the sound plays properly for the PROJECT skin. Afterwards, I tested it with Jhin's High Noon skin as well, because why not? His sounds worked just fine. I have an exam in an hour or so and I just wanted to do a quick test, but there's a clear bug going on here, replicable 10/10 times on Yasuo. I suspect it may have something to do with his Q sound being tied to his voice going off on cast? No way to be sure.

For reference, my IGN on the beta JP server is "Giga" if you need it for anything.
