Yi ult crashing the game?

So I wound up in a weird twilight zone game where we had 2 players speaking japanese in champion select only. Near the 13 minute mark a fight broke out while I was Tahm Kench, and trying to use devour as master yi cast his ult hard crashed the game on my end, forcing me to restart because league refused to allow me to click the box that said that "a critical error has occured and the client was forced to close" o_O
