Critical errors while trying to reconnect

Sometimes my net goes away, I think everyone knows what is that feeling like, so you trying to reconnect. Today when this happened to me when I tried to reconnect I've got a message that said "Critical error occured" and I had to restart the game 3 times before I've finaly reconnected. It happens very rarely but it can be very fustrating while your team has to play 4v5 cuz of this "bug?" I mention that, that this happened to my friends as well. I would be very greatful for Riot would make something about this. [sg-ahri-2]
