Conquest of Cairo still has Spider-Man on the roof.

During the Siege of Cairo, some players are able to reach the roof by climbing steel beams.
Why not set a height cap? Is it a technical issue? Surely players shouldn't be allowed on the roof in either Rush or Breakthrough?
Of course, we should remove the way to get to the roof, but we should also set it outside the area so that players can't get on in the first place.
