Blood moon Kalista Joke/Taunt/Laugh

I love playing Kalista, she is my favorite champ. I was waiting for the Krugs to spawn bot lane so I could leash my jungler and I got bored so I started taunting, joking, laughing and I couldnt help but notice that when Kalista does one of these actions while using blood moon it causes her mask to turn dark and I don't remember it being like that before. It almost seems as if her model has a dark face and the white mask sinks into her face while using these actions. If someone could fix this it would make me very happy. Thank you ^~^
