[SKIN AUDIO] Dark Cosmic Jhin is bugged... Again.
I just played a game of Dark Cosmic Jhin vs High Noon Ashe. When I saw Ashe, it played the voice lines for when you first encounter a general Cosmic skin, not Cosmic Queen Ashe. Attacking her and killing her also played the attacking a Cosmic skin and killing a Cosmic skin voice lines. It happened throughout the entire game.
I think the issue is that High Noon Ashe is labeled as a Cosmic skin somewhere in the system, and that results in Dark Cosmic Jhin reading it as such and playing the voice lines associated with those skins.
