No, the problem are the provinces.
We have, up to a degree, evolved different cultures in different provinces, since many newer provinces were created with the People a minority.
Thus we have traditions that diverge significantly from province to province, with the march basically being the People in name only.
If we cannot unify the values internally once more, each new refugee wave will dillute our former core values.
We basically need better integration processes.
It is a shame LoO never evolved - I'd expect it would have addressed that.
Now, in my opinion, we urgenty need the double main Improve Festivals option just to educate everyone in the values of Ymmri.
And with everyone I mean people who are supposed to be our citizens for generations already.
