On the Mindanao map, opposing country gv'rs are able to drive tanks inside the north shore battery at field A1. Tonight, a rook tank took up residence within the shore battery, killing any knight tanks that drove by. I filmed it, and when I replayed it and jumped in his tank, he was under the shore battery, with a full unobstructed view of the vehicles driving past, and shooting them at will. When I panned up, I actually saw the underside of the shore artillery piece floating in the air overhead. The concrete itself was invisible. We, however, we were unable to see him or shoot him. I have it on film and emailed it in to support. Waiting to hear back.
