Bug got me 25 free LP

Clicked ranked solo/duo queue, then decided I didnt want to try that hard, so I clicked on the normal draft queue. The queue popped (for normals), but it was a dodge, and I went back to the queue. When it popped again, I picked Trundle to practice him jungle.. When we won the game, it had put me back in Ranked solo/duo queue.

Thanks bug? but if I lost and got demoted it wouldnt be a thanks.
