[GAMEPLAY] 6.2 Patch sound bug

Ever since 6.2 patch came out i got this weird sound bug on: Pool Party Renekton and High Noon Yasuo.

On Renekton i can hear a weird thumping sound when using Q and E on minions. On Yasuo sound on Q from High Noon skin is gone (its back to sound from classic)

Is this intentional change or just a bug? If its a bug, when its going to get fixed? pls help ;_;
