I have an issue with a wonder (Notre Dame) not showing in the build list of any city. I can't find it on the map anywhere also (You need to give wonders there own color code in the hex marking system BTW). I look in "Show unclaimed wonders" and it says I have purchased it and so all the others are locked out obviously. I have attached the player log as I can't find the saved game file and a google search just points me to that. Hope it helps. Player.log
