I've seen numerous bug reports about the trading system. In my current game, I get the impression that they have somehow switch flat gold and GPT in AI trade value evaluation. Have anybody seen similar behavior? I'm talking about things like picking a lux and pick GPT which defaults to 10 GPT, then AI will decline. Then I ask "What will you give?", and they offer 2 gold + 29 GPT - which clearly is nonsense, but would make sense if AI think it's offering 2 GPT + 29 gold.
