Really annoying Halo 4 Map Exploit

I have been experiencing very annoying games on this one particular map, Complex. There is a map exploit where if you jump through a specific part of a wall, no one can see you and no one can kill you. I hate playing Oddball and Flood on this map as it is just unfair. Please fix this.

This happened to me today too on Oddball, and of course, he had the objective.
