Just played a game and after coming out of it, it wouldn't load the stats. Me and my 2 friends skipped the stat screen and queued again (5v5 Summoners Rift, Normal not ranked, same as before). We got a game and during champ select all 3 of us were thrown out to view our previous game stat screen. We then couldn't queue until we relogged as we were 'still assigned to a game'.

Same just happened to us. We could still hear the sounds of champion picks and bans so we closed client and now we need to wait 30 mins. Great client.

SAme here

I take an abbandoned 30 minutes for this
