Screen freeze in champion select, lost LP.

I was first pick, when the screen froze and "an unknown error has ocurred" showed up. I could speak in chat and see what other people were writing, but I couldn't ban. Later, the "lag", and the I saw the 3 champion I clicked in were baned. Tho I had 14 sec to pick, in that moment, 2 seconds later, I left champion select for "refusing to select a champion" Lost 3 lp, it's not much, but still annoying.. I think it should be returned
