System of core loss

[Rodak Polak 597]

I think that sholud be somethink like core loss system - if you will lose province, you will not have core there forever. When last citizen of your country will die - you lose core on this province. Example - Spain once controlled Sicily, they get core there (lets say after 100 years) and later they lost Sicily -> when the last Spaniard will die on the any province of Sicily, they lost core in that province.

It looked bad in AoH2 when country that has fallen 500 years ago (and every single citizen died to) still had core to that province. How was that possible?

And since core creation time will be customizable in a json file, the core destroy time should be customizable in the same file.
