Well I tested in 1.14f and I still get civs gracious at -11, and furious at +11, regardless of who has the power lead. Could you give more specifics to what was happening in your game (difficulty level, map conditions, # of opponents, civs that were involved, any attitude changes that had happened, etc.) or send me a save to email@example.com or post the save here so I can take a closer look at it. Nukes: Civs that were not the victim of the nuke will add +13 (if they don't also declare war on you). I haven't studied yet to see how much of this is temporary or permanent, and how much the victim adds on. I had the Celts go from -3 (polite) to +10 (annoyed) when I nuked the Aztecs. Gifts are the same as I posted, with a cap at -10 if the AI has a power lead, and -5 if you have the power lead. I can still get civs at +100 if I continually demand tribute from them. -1 if the amount is small (10 gold) and they are still polite with me, -2 if they are annoyed/furious, or if the demand is a very large amount (10,000 gold). --- Another thing I noticed- For the 'who has the culture lead' point bonus/penalty, it doesn't seem to affect things until you have a few culture points lead (won't take into effect the same turn, or turn after you built your first temple, but will kick in by the time you get 10 culture points, for example).
