I was in a ranked game when this happened, anytime i reconnect i just disconnect. I tried to join at the send to see if the game it self is the problem or the entire thing i bugged. As it turned out the entire thing is bugged. This also happens in ARAM and custom games. I understand that when u use a BETA you should expect these things, but the reason BETA exists is so that things like this don't happen when Windows 10 releases.
