Sad news guys, this game breaking problem still very much persists. In my current deity game there is only Germany with few vassals left and over 30000 points, technologically going somewhere past nanotech era. Almost all of his cities are again painted with red and green faces and there are often periods of anarchy. My points are just over 8000 and I should have no business of winning at all but I can't lose the game if I just keep playing since the Germany is just crumbling away before me. Ai has totally broken down again and lost the control of it's cities. Hopefully you guys are able to fix this. Luckily it happened much later now but it is still there.
