Locking in at 0 seconds = dodge
This happened to me twice, my team mate locked in at 0 seconds and lobby froze up for few minutes then gave me "Connection Timeout: The request to the PVP.net server timed out", but everything loaded in after the error message popped up, so I was able to lock in my champion. But this time, enemy locked in at 0 seconds and it froze up again, and I could not lock in my champion when it was my turn, making me dodge the ranked game unintentionally. I hope this could be fixed soon.
