choose the new champion taliah, game got cancelled and I got a warning for leaving

So I logged in on euw, saw that taliah was able to be bought, hyped as I was I bought her right away with ip. I joined a normal blindpick, got taliah, but for some reason when the game were about to start it just cancelled the game. And I got a leave..... Hope this doesn't affect people who are going to pick her in ranked. Obviously Rito has a bug to fix.
