GAME CRASHED MORE THAN ONCE

Okay I don't understand why there are only a few people who are experiencing this game crash. It makes no sense. All I ended up doing was restarting my whole computer and it worked perfectly. Even so this needs to be fixed or something. My only conclusion is that it could be the type of service provider that we all have. I don't know just making assumptions. I just hope loss prevention can be posted until everyone's servers run smoothly. I hate seeing people lose lp or get reported for a sudden "afk" it's not right. PLEASE RIOT FIX THIS!
