Not really a bug, but since the last major patch and the new textures the manned ack is almost impossible to see. When i go to de-ack a field even when I have Zoom togeled on and am zoomed in all the way you can't tell weather the manned ack is up or has been destroyed until you are 100' away.
I would like to suggest that the manned ack positions have a light collered ground texture (like the old concrete grey, or maybe a light sand color) so planes can tell if the position has been destroyed or not. I am constantly wasting rounds trying to take out manned ack positions that are already down, or worse yet thinking a position is down and then getting nailed by it.
