Loading Screen issue (bug?)

I am experiencing a really annoying issue ever since the current patch came. Basically, everything runs fine, and when I get to loading screen after champion select, it loads up until all players are 100%. After that, it will stay in the loading screen, the loading wheel spinning continuously, and after a few minutes the game would close and return to the client. I don't know why it is happening, I never had it before. It didn't happen to me in all of my matches, but still in a few and now I just got a leaver buster for 5 games. It's unfair! Please, someone from Riot notice this, and also is it just me or is anybody else having this issue?{{sticker:sg-soraka}}
