With the new introductions of base parts and the ability to equip base buildings and turrets while upgrading another base component. I was thinking it would be nice to have something similar in the shipyard.
Here is my suggestion. Why not have it like this. If you have a ship building, Why not allow the design mode to allow ongoing refits with a time penalty.
Such as. If you have a ship that takes lets say 3 days to build and you want to refit an item that takes 12 hours why not add a 50% time penalty for the refit making it 18 hours.
This would allow players to have a ship building while refitting another and kix would still come out on top. If players wanted to coin said refit they would have to pay for the extra refit time.
