Please explain your issue is in as much detail as possible.
In 130 - Troyes in history/provinces
b_brienne is a city now, while b_chaumont used to one and is the second castle in the province now instead.

b_brienne.txt in history/titles
still exists unchanged and has lots of supposed noble dynasty characters now as holders of that city.

One could also ask though if the change from castle to city makes sense, if it was on purpose in the first place or a glitch.

...this also seems to cause their children to have claims on hte city, but this is just an additional
impression which might be wrong and caused by soemthing else.

Steps to reproduce the issue.
see above
Just look at b_brienne.txt in history/titles and 130 - Troyes.txt in history/provinces
and compare with the state of those in pre 3.x patches.
