[Client Bug] Champion Select

During champ select the client tends to bug during locking in both bans and picks. A window pops up that says "There was a problem with locking in your champion. Please try again." But the "Okay" button cannot be pressed leading to a forced dodged queue and corresponding punishments on the player. I've had that happen to me three times the past two days. All the details I can give is that the client seems to lag a bit during the swap between banning/picking players before it occurs. I've been testing my connection and I can assure that it's not the problem with my hub and overall link stability. It's not a major issue, but it can lead to unjustified League drops and Leaver Buster kicking in. I am currently sitting on a 6 minutes prolonged waiting because of that issue.

Hope it helps somehow.
