Adding custom structure to replace ancient_city_center
I would like to have a custom structure I made replace the
city_centerstructure of an ancient city, except when I do that, cities do not generate at all.
To make sure it was working, I replaced the
tall_ruinsstructures instead, and then cities did generate again, but then those ruins did not generate.
What am I doing wrong? How do I replace one part of a city?
Edit: So apparently it was due to my structure not having a jigsaw setting the city center. At that point my structure generated, but not the rest of the city. The solution? More jigsaws.
