0 income!??!?

Is this even possible? LOL

Ofc

Why does this happen and how to fix it??

Not possible

you probably didnt take the capital before this city out of a country, wich means you only get 10% of it's income. it adds up by 5% every turn until it's 50%
if you take the cap, it will increase by 25% every turn till 100%, after that it will increase by 2% every turn until its 150%

if a country looses a lot of inhabitants (via huge battles or by bomber wich are extra devastating) it's income decreases too, like in the pic i showed you

Thnx much
