So i am playing England with France under PU. I convert to Protestantism even though the prestige hit could break the union if my king dies. However, my king was around 25 years old. I convert and quickly gets to 0 prestige again. But then out of nowhere the union breaks and I am at war with France, but it is not an independence war, it is the conquest of Armagnac. I got CB to restore union, but then I will have to wait another 50 years (they broke free right around the 50 year mark, does this have anything to do with it?). So anyone knows how and/or why they just broke free without an independence war?
