[Client] spell selection not working, and more

In champion selection, I picked smite, for jg. Instead of switching to smite it displayed a spinning loading circle. Countdown timer was nearing the end, so I exited the game to dodge the match because I suspected there would be more bugs, maybe a server issue. Opening the game again, it froze twice on the 'league of legends' insignia phase, before the login menu. First time, I closed it with the 'LoL not responding' popup. Second time I went into processes and saw this client was running in two instances, so I closed both of them; after that the client worked normally. However it attempted to reconnect me to the match -that I exited while champ selection timer was still ongoing-. So the client neither selected spells properly, nor exited properly, nor restarted properly.
