Autofilled during promotion. Twice.

I entered my promotion to gold 3 today, and I got my main role on my first game and lost. I figure, oh well, at least I have my next two games to play out. In my next game(I ALWAYS queue top and mid), I was filled support. I was pretty upset about it, although my teammate allowed me to play mid lane. Unfortunately, it cost me my promo because someone on the enemy team had taken the champion I main and was going to play mid lane. Although I did get my role from someone nice enough to swap, this shouldnt have happened.

Also, earlier today, my friend(CytheGuy) was also autofilled during his promotion to Silver 1. He too, had lost his first game, and autofilled support on his second(where he queued top and bot, as usual).

This is an extremely frustrating bug and I do not believe this should be happening! We both had a(complete B.S.) Autofill Protected message. Fix this bug. Best Regards, RapidCombo
