Not sure what to make of this, but I asked polynesia what he'd give me for copper and he offered $5,600, elephants, resin, and about 25 different ships including galleys with 3 navigation promo's, Decaremes/triremes/Quinqueremes all with lots of promos too.
Obviously this is bogus and totally a one-sided trade. Not sure if you would some logs or something, I think i've got them on. Let me know.
* He does have 80K in the bank so maybe its not THAT bad a trade.. maybe he really needed the copper to upgrade his entire army, doubt it though since i've noticed in the past that the AI pays way too much for military resources such as copper/iron/obsidian/horses etc.
The save game in which I can ask him that question and get that response please.
