Importing cost is tied to national support.

[guilemouse]

Noting for the future:

Importing cost and goods should work off the national support reputation.

See OT_fnc_support, everytime a town is called it puts the stats into the server's total rep.

server getVariable ["rep",0]

import should work with this line plus some stats in player character sheet.

Possible stat cap to a town's support cap being 1000, or something smaller so the server's support cap is never exponentially big.
