ever get "stuck" OTW the tower because of lag?
IIRC it was stated that the bar dar you are seeing was a result of the dudes stuck in limbo from lag after dying.
if you recall when you die, you zip to the middle of the map for a split second, then to the base you last upped, or if that base has been captured the lowest number base your country owns.
it was most obvious on the AKDESERT map where squiddy was in the center of the water... you would fly there and get stuck sort of in he tentacles.
at least thats what I remember of it being discussed before.
