[GAMEPLAY] Black nothingness on Summoners Rift. (Found with Galio)

I was just screwing around in Practice Tool, trying out my new Hextech Galio skin, when i stumbled upon a Bug at the Fountain, (Blue Side) where if you look down, you can't see anything but black. i checked it out with Galio's ultimate ability, and i was right, there was a huge gaping black hole at the bottom of the map. I made a video about it on Youtube, i put the link in the "Link" part of this discussion. RITOPLSFIX
