EXPLOIT/BUG - Players can reach very top of roof on Cairo Conquest

I only saw this once, but there is apparently an exploit that allows players to get on the very top of the building on one side of C on conquest on this map. I'm talking way up there, there isn't a natural/intended way to get to this point, and I only saw it once. Consider adding a ceiling to the map, where this building top registers as not in playable area and auto kills players unless they get out of it just like other unplayable areas.
