1) Seperate Worlds for Ground and Sea vehicles.

Ground Vehicles: The terrain on the movecraft server only has a few areas that are really similar to tank combat on ccnet. I believe to rectify this a ground arena should exist, existing in a largely flat sand biome to really mimic the Sahra desert.

Sea Vehicles: Literally an open water world, nothing else.

2) Sinking ships dissapear.

Upon a ship sinking, it just disappears or sinks a lot lower to prevent ships debris on the surface.
