Hello all, I'm new to the forums - have been playing since Civ III. I'm trying to confirm that resources that you import either from a city-state or another MP are not available for you to trade to another MP. Often I'll have way more horses/iron available for building units than are available when I go to trade. I've also noticed the same thing with luxuries - sometimes when the trade screen shows I only have one to trade, it doesn't show luxuries imported from city states. Is this correct? Is there any other reason for having less resources available to trade than to use?
