Failed to select champion.
Weird this is the second time I've been ejected from champion select due to "you have failed to select..." when there was still several seconds on the timer. Just starting my promo series and get kicked with 7 seconds left due to failing to select.
Also don't you supposed to lose 10LP for "dodging" on a series? I only lost 3, which I'm happy about, but still seems to be suspect client behavior.
