Hixus no longer disables if Yarok is on the AI side. Had two matches in which I encountered this issue.
edit: left out another thing, if the AI had a creature disabled by Hixus when Yarok is cast, then that creature stays disabled. Any any creatures afterward are also unaffected by Hixus and can attack freely. I was not able to remove Yorok so I do not know if the effect ends when he leaves the battlefield.
