Ranked Position Trading BUG

Alright, so my ranked game started and I was ADC/BOT.

Our JG played Jinx and went bot, so three people were in bot lane.

After the game, it said I traded with JG and then charged me a game in JG. I haven't even played a provisional game in JG yet.

I was playing my bot lane then the matchmaking thought I swapped with JG, when I didn't. All because she went and played bot lane with us.

UPDATE: This bug charged me my first provisional game in JG!
