Invisible Allies Bug

I recently experienced a huge bug when I played with Rumble after downloading 6.4 on my mac. For whatever reason, I couldn't see any of my allies, they didn't reveal terrain on the map that they could see, and I couldn't see them on the minimap. I could tell they were there if they casted an ability. For example, I could see Thresh's death sentence when it was being cast but it appeared from nothing. As a teamfighting game, the game becomes much more difficult if you are unsure whether or not you are even in a teamfight. This is perhaps a related bug, but I was also unable to teleport to turrets for the duration of this game. I could teleport to wards and minions just fine.

I haven't played a game since my Rumble game, so I don't know if it is a problem with Rumble's update or a general update issue, or what. Has anyone had any similar issues and if so, how did they solve them?

Thanks,
