Is there a special way to do it? i click "duplicate" on the Vliia from he Sierra MAdre but it doesn't do anything.

I need that worldspace because for some reason it's "ground" is perfectly in-line with the Madre kit pieces on a comfortable 32-grid snap, but when i snap to grid on a newly generated map (at the same height as the sierra madre, 1000), i have to set my snap to an uncomfortably precise "4" setting. IF i can't copy the Villa, is there any way to fix this, perheps off-set the grid that the pieces snap to?
