[bug][0.75] A.I settling on... Iron Ore ?!
As the title says...

Magnar has founded a city just on an Iron Ore ressource. According to City Details, there is no grain, no essence, and no production either on this spot (which seems quite logical); however , there is a city on that tile (which indicates a strange behaviour from the AI...)
Basically: AI is settling on tiles with no tile Yields. NOT good.
