Ancient Center of Paphos in Covocle, Paphos, Cyprus is missing. Along with Trakai Castle in Trakai, Lithuania. Also the Falun Copper Mine in Falun, Sweden. The Belfry of Bruges in Brugge Ouest-Walloie is missing. Lastly Gelati Monastery in Kutaisi, Georgia. All of these monuments are just gone. Not sure if any others are missing or not, but they're just gone and not in the game now. I believe they're all the modded in monuments so that might explain it and due to the mod being outdated.

It sounds like they added some new monuments. I'll get the mod updated soon
