Got moved from game to queue [crash?]

Hey guys. I was playing some League yesterday. It all started normally. We chose champs, waited in loading screen and played for around 8 minutes of the game. I was playing top lane as Darius vs. Lissandra and when Master Yi came to kill me my game froze. I thought it had to do something with my internet connection so I turned it off and on-That didnt help at all. My game got closed like if I left and instead for reconnect button I got pushed into another queue immediately. The other game was loss and I lost only 14 LP from those "2 games . I was curious if this is known problem or if the game ended for all my teammates and enemies as well. Here is sort of a proof that I was in game and in queue at the same time: http://imgur.com/N6DvD8n Not really sure how to reproduce this...

TL;DR:Got moved from existing game to a queue.NO LP penalties for the game I got kicked from.
