Cut cameras don't affect new AI view

[Frank_Stein]

This may or not be a bug, hard to tell on my end if there was just another camera covering the same area.

But I was playing a round, and someone was cutting cameras but I could still see the area just fine

Meanwhile, a blob was I think destroying cameras in another area which did, in fact, create static there

probably fixed now. Sometimes areas without any cameras in view wouldn't update their static overlay.
