See the picture. Playing on the beta, my PUs have been rebel factories for most of the game, spawning pretender rebels seemingly every 10 years. I don't know why, but they are. In this instance, I got distracted fighting another war and didn't notice a 20 stack of Portuguese pretender rebels successfully sieging down Lisboa. Portugal is my PU. If these rebels enforce, my PU will break as I understand it.
My questions are:
1) In the case of rebels enforcing demands via controlling the capital, can I prevent that by remaining at war?
2) If the PU breaks, will I get a Restoration of Union CB?
I'm playing Ironman, I unfortunately cannot reload far back enough to correct this mistake FYI.
Cheers.
