[CLIENT] Kicked out of champ select with 8 seconds on the clock?

Today I got kicked out of the champ select with 8 seconds still on the clock, the client kicked me out because I haven't locked in yet. It was a ranked game, I lost points because of it and had to wait 5 minutes before joining queue again.

It is not the first time this has happened to me also. I don't know what causes it, but it would be nice if it got fixed..
