I belive there is an issue with national trade goods, i am SA with maxed coalitions and play mainly for the wars. Looking for marble 22 targeted attacks (of the four nations)…. 2 turned up, a single war consumes 20 for 2 coalitions. A total of 60 specific trade goods every 2 days are needed for coalitions. My suggestion is guarantee at least 1 from the targeted nation & then go random…. Or look at what is already in the store and offer what is least
