Guys i found a funny bug! 6 player in team builder!

i went in a room as mid lane , then my wifi have problem. So i think system kicked me. but not show in my client. After i get online, i told them i was offline. then they said WTF you already left the room?! i dont know what's going on either because on my client i still in the room. then they told me i got another mid lane player. so we dont have adc in room but we got 5 people!1 sup 1 top 1jg and 2mid lane(one is me ), and still we have a place for adc !that's mean maybe we can start a 6v5? i dont know because we start another room not try this bug. i'll post the video late, because the game is started :)
