Blacksix - Fix multiplayer play & net-code

[TonyD]

@ hc_wolf: I tried your suggestion, but it does not work. The autogen for the basic trees does not function, only the high detail LOD. If you start the quick mission over Dover, the trees that are present are those that would be loaded with whatever range setting for your aircraft in the starting position. If you fly inland they do not generate at the limit of original range, only the high detail final render in a LOD circle very close to the aircraft does. Thanks anyway though
