Starting a ranked match, and as it is about to go to the loading screen it just ...doesn't. Same thing happened to me a few times doing ARAM's on the normal servers, but never had it happen to me outside of custom game mode like this. (My PBE nick is Severian PBE). I havent closed the client, or tried to dodge, so I'm still in picks/bans.

I don't know if this is a normal known bug outside of custom games, so I'm reporting it just in case. Hope its not a duplicate, but I'm not in a position to start searching right now.
