"There was a problem picking your champion" during banning, well before time runs out.

Simple*, yet annoying bug, that struck me pretty hard the last few games (can't wait for the long queue times). I go to ban during ban phase, click a champ (i.e. Jax, for example), and click away - nothing. I get a pop-up of "there was a problem picking your champion" and then get kicked back to queue, -10lp and a long queue time. Any ways to mitigate this would be nice.

*A minor disclaimer, simple in concept - I'm sure with networking and all that (the one portion of code I am glad to say I never touch) it's anything but.
