If you trade goods away, do you still get to use them yourself?
How long does the trade last? (I'm assuming more then one turn, and less than the rest of the game)
Also, something happened in one of my games. I captured the Drengin homeworld, which had the Hull Plating goods. They became available for me to trade. Later, I disbanded the colony to prevent the Drengin from capturing it back, and I was still able to trade the hull plating.
