Jhin's bug (skill effect)

Helo. I started to play on EUNE again. I got into a game as midlaner as Jhin. I was with the origin look. It was a mirror match, enemy had an ADC Jhin with Highnoon skin. If the enemy jhin was visible (not in the fog of war), then my: Q -s voice. W - s animation, and passive on-hit effect icon. E - s bloom animation. R- s voice. They got replaced with the Highnoon skin effect/voice over/animation. As i said, i was with the original Jhin skin, and it was confusing a bit. Haven't received such a bug on EUW yet.
