Played a few games now with the patch. AI on emperor seems worse. They don't build as many units, and attack with fewer. Then they refuse to end the war, even when down to one city and half a unit, usually still asking for GPT. I offered 2 cities back to the Poles in one game, she asked for GPT from me as well to end the war
Also, AI settlers going off unguarded to be picked by me, barbs and other AI while five units protect their home city. I have one game I'm playing where Eleanor and Alex are both next to me playing capture-the-same-settler for a hundred turns while at war. They aren't attacking each other's cities. They just follow the dang thing, while it ping-pongs around no-man's land between them, getting left unguarded after capture.
