Troopship cost

[DanTheTerrible]

I noticed there seems to be a discount when I build a troopship, which is a transport loaded with a tank, compared to building a tank and transport separately. Is this intentional? This is at a planet without a shipyard and it's discount. Metal cost is the same, but the wrench cost (build time) seems to be given a discount equal to 25% of the tank's separate wrench cost. If you build at a shipyard, does the shipyard wrench discount apply to tanks? If not, do troopships, which are partly tanks, get the full 30% discount? How about Gremak marauder units?

Since the loaded ground troops are part of the ship, I expect that it does get the shipyard discount.

This probably doesn't make sense, but it doesn't bother me sufficiently that I think it would need to be changed.
