I first came to attention of this bug when others noticed that a certain nation has a bonus resource displayed on their nation page that they do not meet the requirements to have.
The bonus resource is Affluent Population and the nation only meets 1 of the 4 required resources.
Affluent Population Increases number of citizens +5%. Requires Fine Jewelry, Fish, Furs, and Wine.
This is the nation who has bonus incorrect resources displayed: http://www.cybernations.net/nation_drill_display.asp?Nation_ID=449862
