@Developers: I tried to join a special scenarios tournament (beta) but I'm advised I must have a prestige rank in each of the expansions to be allowed. I have prestige in Seafarers, Cities and Knights and Basic. but cannot join the tournament. Why?
Plus one on all of these points! The AI is luggable terrible, even when using “Master” players.
In addition to all the ridiculous behavior noted above, my wife and I have noticed a few occasions where once the AI decides who they are going to “pick on” with the robber, etc, they rarely change their minds, even after significant lead changes, and will continue to rob from the same player for the whole game.
