Yep well spotted, they forced you to release the country of Wolgast, and that included your capital. Also holy shit I just noticed that
@Dan is back. They made you release Dan
What's more, he immediately allied
@Abizzz, so he has a decent ally for once. He's also an Elector in the Holy Roman Empire, which means he gets to vote on who is Emperor!
What a fecking hero.
So yeah, you lost a few provinces
@Dr. Dwayne, but it's not the end or anything. They also didn't directly take most of them. In a way you were lucky to be at war with the Holy Roman Emperor, because it's in their best interest to make sure there are as many different countries in the Empire as possible (they get bonuses based on the number), so he didn't really want to conquer you.
