This is what did i found when i tried to join a tutorial game in Summoner's Rift: It just freezes there and you cant hear the announcer telling you the rules of the game (look at the time: 3:14 min); It just stays there until:
1) You leave
2) Kicked by LeaverBuster
All you have to do to reporduce the steps are joining to a tutorial game within Summoner's Rift (Battle Training)
I hope this to be solved. Thanks Riot!
