Right now I am playing for a culture victory, and I stopped research for a long while now. Sitting bull has a dozen technologies that I don't have (and he has all of mine), yet when I try to buy techs from him I see the message "we fear you are becoming too advanced".
All other civs are ok to trade tech, so I don't think I hit some invisible limit... and as I said he has over a dozen techs on me. Broken AI?
