Client Issues caused a Leaverbuster and I am really upset this can happen.

Crashed mid match and got a Leaverbuster warning. I never afk from match until today when I got force disconnected by the PC cafe I am playing at when the LOL client just decided that it was corrupt. Will attach google drive links to show. No error message visible, just kicked from match before loading in and initiated full repair on one machine, autorepair on other machine. Happened to the guy I was sitting next to as well.
