Recruitment of units in regained areas

[Rodak Polak 597]

In my opinion, if a country lose provinces, and in the next war it will occupy these provinces during war, it should be able to recruit units from them, because it is still its core province and its compatriots live there. My idea is this:

1. You can recruit units in occupied provinces during war if these provinces were once your property and they are still your core provinces
2. Core provinces should stop be your core provinces after 100 years when you lose them (imagine that Mongol empire still have core provinces in Baghdad after 700 years after the lose of Bagdad. It is unrealistic that Mongolia would have territorial claims to Baghdad after 700 years)
3. creations of core province and loss of core province should last 100 years

Creation of core province in colonized province may take longer. Maybe 200 or 300 years
