In my current game (151.7), I'm playing Germany in Marathon speed. Ramesses II, who is "Afraid" of me, keeps asking for an Open Border deal, but when I try to accept, he claims it's an unfair deal. (He'll accept it, if I give him some gold as well.) It feels like a bug, since he's the one that initiates the trade. EDIT: Another issue I have with trading, although this may be a bug with Civ 5, not your mod: If I during a trade try to make a deal where I give a luxury and get more than 10 pr. turn, the AI gladly accepts, and then, when I go and check the Deal History, it says I'm getting only 5 pr. turn. That's really annoying.
