I'm at war with a country. I destroyed a city (it has 0 health) but it isn't letting me annex/create a puppet city out of it. It keeps saying that it's still owned by the Aztecs. Every turn it is able to harm my units and regains health.
If I attack the city after it's out of health, the attack animation plays but the red
-20 health thing doesn't show, and their health bar doesn't go down.
The city I'm destroying isn't their capital, and I haven't attacked any other cities.
The civ I'm trying to destroy is the Aztecs. I have the brave new world DLC.
