City of Wonders 3

These are the mod I'm using. I played with them many hours without crashing but after my dynasty head count reaches over 1000 the speed of the game was unbearable. Then I found your mod and started a fresh save. I played for 3-4 hours with amazing speed. I went to bed and the next day when I tried to start the file it crashed. I had four save file from that game and none of them opened.

Now I removed City of Wonders 3 and restarted a new save. As you can see nearly all of my mods are quality of life. I don't believe they're uncompatible. The only culprit is city of wonders 3 because it adds new cities to deleted region of the map.

I hope it'll not crash this time. Late game lag is sucking all the joy out of the game. Your mod is doing wonders :).
