Hey Jurand Are you planning to rework traits ?
I ve been scrolling in and found some vanilla unchanged traits or atleast this trait that never popped up in my 100 turn campaign I hope it will help you on further work.
GoodBuilder
Triggers. Only building Walls/Castles does influence noticeable otherwise NOT
Same goes with GoodAdministrator trait
EDIT: Senile trait makes older people bad at anything it feels like you need to suicide him. I think Authority and law shouldn't or minimal be affected by it. If not mistaken later when baby is born and fathers authority is below 3-5 then he gets bad traits cause of fathers authority. One more thing Senile trait progresses very quickly and at 60years he will have 3rd level senile trait.
