Playing the map with the lighthouse on it; this little kid can't remember his gamer tag will check players met later. He was floating around the map near the lighthouse stuck in the air and invinsible, also he said in the after game lobby he and friends were inside the walls of the lighthouse.

He clams to have found it by accident, may be but he kept doing it all match. I think it is something to do with the fence/jetty things on the left of island (in water) as you look at the lighthouse.

Crytek fix it
