[Client] or [Gameplay] Possibly a Bug with Galactic Nasus? Mac Client

In the past 2 days, I have played two ranked games with Galactic Nasus where I crashed. The first one, I crashed and had to re-log to rejoin the game. At the end-game screen I was greeted with a 5 game low priority queue despite my reconnecting. Second game I played just yesterday. I got in-game, helped the jungle leash and when I got to lane I crashed. I kept on trying to reconnect, but sometimes it got to 100% and then crashed. I would like to add that there was nothing wrong with my internet since it was still loading up the reconnecting screen. I was unable to get back into the game, and was given another 5 game low priority queue. I'm not sure if my playing as Galactic Nasus had anything to do with it, but it has only happened when I've played as him.
