Not real bugs but maybe two points that need some discussion: 1.) If you want to improve the relations with a civ, just declare war on them. When you conquer a few cities, make peace and then liberate the cities, they will love you, which seems strange. 2.) Imho, the absolutly most powerful wonder in the game is King Richards Crusade. Here is why: The Crusader are all lead by a general, which means they can get the Heroic II promotion. In a good specialized military city with a lot of free XP, the can get almost instandly to that promotion (or close to). In my current game I have ober 1000 Turns (!!!!) of golden age left. And it could be more if I wanted, since the crusader are still there and there are weaker enemies around. And even if not, they can be upgraded... So I suggest that you remove the "Lead by general" promotion from them. But then there still is the problem with heros. I conquered 3 different Native Cultures, which is no big deal for a leading civ. But I easily have 10 Heros with Heroic II promotion at one time.
