When your client crashes

that moment when you get into champ select... you're waiting for the other people to lock in and POOF your client just closes and you get a nice -10 lp and a 30 minute ban. please fix this issue. i've had this happen to me 3 times now not when i was in champ select but just randomly clicking something in the client whether it be joining a lobby or look at my loss streak in my match history.
