This is a new game with the 1.8 Opt-In. I am not using mods.
There are two problems with the trade window when the AI initiates the trade.
1. At the top of the screen there is no Leader Name. If I initiate the trade, the name is there. If the AI initiates it, the name is not there. When I back out of the window, the name appears. When I go back into it, the name is still there.
2. The AI is always shown to be unhappy with the trade despite being the originator of the trade. If I click on Accept, the trade is completed without a problem.
