Modding

Hello everyone, I have a problem. The Dragon Utopia is always empty, on any map, under any circumstances, it says: "Long ago, this city was the home of dragons and their treasure. Today, a cold wind blows through the deserted streets..."
Of the mods that affect the building, only "TE" is installed, and I also changed the creatures, their quantity, and the reward for victory in the game files.
Does anyone know what the problem might be?
