- Added a game rule for tribal rulers to construct buildings in castle holdings
- Game rule unlocks an tribal innovation ("Conquered Castles") for cultures to research that allows a tribal culture to unlock the ability to construct a castle building inside of a castle holding, but it's at an increased cost. Game rule is on by default.
- The following heritages have this innovation unlocked at game start (1084):
* Sturgic, Battanian, Khuzic, and Nordic (Byalic)
- Fixed wrong Swadian and Rhodok cultural heritage
- Fixed Sturgian Unification decision
- Fixed bad localization in ck_wars_l_english.yml
