"there was an error"

Seriously, $%&#($&($ I pick heal at 1 second left and it says "there was an error" like... lock it out then, but please add the same "save masteries?" opportunity to summoner spells that you added to masteries when they close in the last second. happens way too often. I never even have time to pick my skin. Also you can ban a champion like 4 seconds after the timer ends, so why can't I change my summoner spell at 1 second... maybe add 2 seconds to the game countdowns. Thats literally all I need extra.
