1451 Venice. I'm not normally a homicidally aggressive player, but after taking Ragusa I somehow manage to get into four wars simultaneously and, while still still at war, acquire some vassals and a coalition consisting primarily of Austria, Hungary, Naples, and Genoa. No problem in that, I'm having a blast, but it's all gone a bit peculiar.

First I take the irresistible Cyprus mission. After I've won a Pyrrhic victory against the guarantor Mameluke fleet with its five heavy ships to my none, I get bogged down in a stand-off when Cyprus apparently refuses to be annexed unless I defeat the Mamelukes on land - blockades just aren't enough.

While this is going on my new ally France calls me to arms in the HYW, an offer I couldn't refuse. Then of course the entire Royal Navy and English army decide that I'm far more tasty than any of their French holdings. Fair enough. Fortunately the up side of this is that the city of their heart's desire turns out to be Corfu. No problem Henry VI, go right ahead.

While dodging the English fleet shuffling reinforcements to Corfu I try to vassalize Byzantium and their ally Serbia to pre-empt the Ottomans, whose initial mission was Rhodes. Unfortunately by the time I've occupied their provinces, the Ottomans have declared on them too, so if I vassalize Byz I'll be dragged into war with the Ottomans - with their army on the European shore. In any event after the Mamelukes my fleet is still rebuilding up to parity with the Ottomans.

Finally, by the time I'd taken Serbia's provinces Bosnia had declared war on them, and under the old EU rules if I'd vassalised them while at war Bosnia simply would have taken them back while I was at peace. Anyway what I instinctively did was to fabricate on Bosnia and declare on them too. In hindsight I think I probably missed a trick here.

I was lucky enough to peace out with a mere concession of defeat against the English. Then I vassalized Serbia. Then because I couldn't vassalize without committing suicide by Ottoman cop, I took all Byzantine provinces but the capital, intending to release Byzantium as soon as the Ottomans took the capital, by which time I'd have rebuilt the fleet to defeat them at sea. Happily Cyprus finally agreed to be annexed just when I was about to abandon the whole exercise, I think the five years was up. All this land has resulted in the coalition. Not planned but not unexpected in the circumstances, fair do.

My problem is this. I'm still at war with Bosnia. Bosnia is fully occupied but refuses to peace out with Serbia, which is now my vassal. If I vassalize Bosnia, I am warned I'll be dragged into war with Serbia despite it being my vassal. I couldn't quite believe this so I saved just so I could try it out. Sure enough, if I vassalize Bosnia then my Serbia de-vassalizes and goes to war with me.

I can work around this such as waiting until (if?) Bosnia-Serbia peace out, or better just re-occupying Serbia and feeding it to Bosnia to reduce my number of vassals (might be good value as my first March?), despite it wasting a year or so before I can do anything much else. But perhaps my best option is to approach it similarly to my Byz solution: forget about vassalizing Bosnia and transfer occupation of all but the Bosnian capital to Serbia in the peace. I don't much care how the rest plays out. All good fun.

However my question for the panel is: is this strange Serbian-Bosnian vassal/de-vassal situation WAD, a bug worth fixing, or a bug not worth fixing?

Your vassal Serbia is in a war and you aren't in that war? How's that happens? Normally that seems a bug. If you vassal someone, who is in another war, you will dragged in that war. And a vassal cant start a war.
Serbia can't accept / send a peace request as vassal. So Bosnia-Serbia never ends, unless one of the two does not exist anyore. I would full annex Bosnia and sell all provincies to Serbia. Or if you want to have Serbia and Bosnia both as vassal: Release Bosnia as vassal when you are at peace.

Sorry, I'll put it more succintly:
- Venice at war with Serbia.
- Bosnia DoWs Serbia.
- Venice DoWs Bosnia.

At this point each of the three is in separate wars with each of the other two.

- Venice vassalizes Serbia. Venice cannot be dragged into war with Bosnia because Venice is already in a war with Bosnia.

So now both Venice and Serbia are in separate wars with Bosnia.

So if Venice vassalizes Bosnia, both are dragged into war against Serbia despite nominally being a vassal.

[EDIT: I've now discovered that I can't change my Bosnian province occupations to Serbia as part of the peace deal, because Serbia is not in the same war with Bosnia. I'll have to feed them to Corfu instead!]

I LOL'd at this. The exact same thing happened to me with Venice.

It is indeed weird with the vassal warring case. I have also had this same scenario play out.

The answer to getting around it is to fully annex all the Bosnian lands first, then after the war is ended, release them as your vassal.

I think the issue is/may be that whereas in the past you were immediately the war leader in such cases, now you aren't and as such, the fact that a country is your vassal is secondary to the fact that they are still the war leader. I see this as a side effect of their changing how war leader selection works.
