OS X Client random freeze? No match history, long queue times.

I was playing a game and doing pretty well, when suddenly the game froze. I had just started walking from the nexus towards the outer turret. I right-click beside the turret and the game froze. I could move the mouse, but there were no sounds, and my friend reported to me (who was playing the same game) that I had walked towards the turret and just stood still, taking attacks from the enemy Gnar and then just staying still. It was not until I had restarted my computer that I started walking towards base and my friend received the 'summoner disconnected' message.

When I rebooted into OS X, I immediately logged into League. There was no prompt to join the game that I had left. I went to spectate the match, and it said the match did not exist. After the match, my friend did not see the match in his history. He was using Windows.

So it possibly affects more than just me, but there are quiet a few problems. I just finished writing about my experience with not being able to join queue for 17 minutes now.
