Muscovy game. I am at war with Sweden who is independent of Denmark, but at war with them because Denmark wants to restore the union. I have all of the Finnish cores taken and am attacking my way towards Stockholm. The plan is to get Sweden to return as many cores as possible to my vassal Finland. All of a sudden, white peace. Sweden has surrendered to Denmark and is now in a union again. How the hell does that end my war? I could accept if it brought Denmark into the war against me. But the war is just over? Just like that? I get nothing? No chance to even get one province for loyal Finland?

If you vassalize a country at war with someone else you enter their war. So why if you restore a union do they just escape the war they are losing quite badly with no consequences? Not cool.

For some reason, the formation of a personal union disrupts all wars. No idea why.

Is this WAD? I didn't think so.

The same happened to me at 1444 when I was at war with Lithuania and suddenly Poland got a PU over Lithuania and then the war ended with a white peace..

This is probably a bug that should be reported in the appropriate forum.

Yep, if you win the HYW as England while Burgundy has declared war on weak France, the France-Burgundy war instantly peaces out.

It might be intended, because technically you are at war with a particular monarch or government. Still though, sounds like a bug.

That might be WAD as it was also the case in recent versions.
Actually it was worse before:

Once in a war against Russia to finally vassalize them, war goal is to take the capital. Russia then falls under a PU with Britain. Britain becomes war leader but Russia drops out of the war! So I have no chance to take the war goal and am in a neverending war against Britain. I think that was back in 1.3 or 1.4. The current system isn't perfect but at least better than that ...

I actually had the exact same scenario today but peaced with sweden before Denmark could restore. Glad I did even though i didnt return every finnish core.
