Champ select bug caused me to dodge a ranked gamer

This happened to me once and a friend once. What happens is that the screen is frozen and is clearly bugged. The buttons make sound and the sounds from the champ select happen but I am unable to see what's going on. I had 0 lp gold 4 and it made me dodge so I hope i dont lose anything. Im not sure what causes this but it may be something to do with being messaged and getting a game at the same time.
