Working with map objects without using the editor.

If there was a way to adjust the properties of map objects without using the map editor. I'm trying to create another town with characteristics identical to the original, but with a different model. When copying the properties of a standard town, half of the options are reset (Combat). And all the settings inside are also reset. Because of this, it's impossible to attack the town. I managed to solve the problem, but if there's a fort built in the town, the game crashes immediately. Also, it's impossible to end the day because it also crashes. Manually re-setting the properties is very inconvenient and takes a long time, and it's not even certain that the changes will solve the problem. Is there a way to work with the same objects but through the game files?
