Black Screen

Riot you gotta fucking fix this bug or whatever the hell it is because this happens way too often now. I know I'm not the only one getting this but I start a game and then right when we are supposed to get into loading screen I get a black screen and I can't close it and it forces a remake making me lose lp when it's not my god damn fault. Shouldn't be losing lp because you guys dont know how to keep this from happening.
