just found one more cheating:
an AI city without any street, harbor, airport, railroad to an other
destination (not of same civ and not to an other civ), total isolated, had
*all* resources which the respective civ had. Means all citizen are happy by
luxus and they can build all units that they can build at other cities with connections.
Although this city should have no strategic or luxus resources without
connections to someone.
Found it by spy and made a screenshot (if again one will refuse this)
