[Minor bug] Kayn 's voice not changing to Raast when watching game replays

I was looking back at a rather fiesta of a game and just noticed that our Kayn , who went with Raast form was still grunting as though he hadn't changed his form. I'm unsure whether Shadow Assassin form will produce the same bug, but when watching a Raast in spectate mode, he will grunt and speak like Kayn with no form change
