The WoC is being caused by a Luchiurp mage in Gostai. There are three mages in the city. It is the second mage that is causing the WoC. I fixed the game by eliminating two mages.
I tried changing that mage's AI script, I tried 5 different scripts. No good.
The 'problem' is that those two mages are quite powerful - eliminating them can have a material impact on the game.
So, I recommend playing the game I attached. At the end of the turn, you can give back two powerful mages to the Luchiurp and you will probably be fine. I can do that for you, but I would have to play your Civ for one turn and you are in a ciritical spot in your game.
Therefore, I recommend playing the save, and finishing your turn. Give the Luchiurp two powerful mages. If you don't know how to do that, or don't want to peek in the worldbuilder, just play your turn, send back the save, and I'll do it for you.
Best wishes,
