AI Privately Trading
When playing on single player mode, against two AI players (everyone on Master), I sometimes experience the two AI players trading with each other without offering me the trade. In this case, my "do not trade with me" button is not on, so I SHOULD be seeing trade offers.
I agree and have pointed out this bug in the past. The response I got was "it's because you don't have the requested resource or don't have any cards" - which is BS. There are plenty of times when I don't have the resource or don't have any cards when I _DO _ see the trade window!
