I have manuelly moved the ships in 3d space before, you know moving them above and below the grid around a planet, but its not working anymore for some reason. I have used the "~" button and I have tried pressing and holding "D", but neither initiate the 3D move. what is it called on the key bindings menu? maybe it got erased somehow, but i dont know what its called on the menu. any help is greatly appreciated, i like moving em in 3d
