Eu4 Personal union Bug/Exploit

[Popenomore]

Hi all, i currently play a multiplayer game every week and with this particular group there is always something shady. This week we had Poland attack Hungary (who was under a PU under Austria) and Austria was not called in despite being head of the PU .

I'm wondering if anyone know how he does this. it has really messed up our multiplayer game this week and the host says its just a "bug"... But he did this 3 times in the same session!

Attacking a junior should always call the senior. No bugs that would prevent that as far as I know.

The only thing other than shadiness that I can think of is that when you acquire a new PU, they aren't called in to any other ongoing wars you already have. But when you gain a PU their other wars are either cancelled or inherited by the senior. Can't see any legit way that someone can attack a junior without the senior being called in.

@atwix is the true expert on PUs, I'm just very good at getting and using them, (which I learned from atwix) he might be able to shed some light.

Are you 100% sure that the PU was active before the war was declared?

Is Hungary the war leader?

A nation at war cannot fall into PU naturally.

To me it sounds like the same bug where your CN gets DOW'd and you as overlord not getting called in, maybe it's the same issue here? Just guessing though.

It's Hungary and Austria, there's an event chain. I don't know if war stops it though.

Being at peace does not seem to be a condition.

There is a bug? In recent patches (I still play 1.21.1)? Your CNs can be DOWed by other CN, and you are not called but are you talking about a situation where your CN is attacked by an independent nation?

That's WAD.

Wish I could sum up in a few sentences how much I have complained about that one, but I'd just end up writing a 20.000 word long rant.
Same goes for CNs being able to sign a separate peace, leading to me having to no-cb and force vassalize natives because they were locked in by my CN who kept signing a separate peace without ever fully annexing them.
Can't hand over territory because they're out of the war, can't take it for yourself because those provinces are landlocked.

Absolute rubbish. It did make all costum nation related achievements a walk in the park though once you start abusing the mechanic like there's no tomorrow.

Still salty about how easy any start in America is atm. Or almost any achievement on recent patches for that matter.

Yes he was the war leader and only in the war the ottomans no one else

A nation at war cannot fall into PU naturally.

They can by event or by a Claim Throne war, though.

There shouldn't be any way that a Junior can be in a war without the senior also being in it. Although, since the reverse is not true maybe there is some edge case where a junior is in a war and the senior can't participate due to already being involved in another war that also involves one of the participants in the war that the junior is in.

For example - what would happen if:

France are at war with Austria.
Castile is at war with Austria (separate war).
France then DoWs Castile for a claim on their throne.
France wins war against Castile while both are still separately at war with Austria.

What happens? I'd guess that the Castile-Austria war would just get cancelled.

Oh really? I thought it was a bug because people seem to keep complaining about it, not getting called into a war of your subject sounds buggy though, but I'm sure you know more about it than me.

I've seen the thread pop up a few times on the board as well, but no. Complaints don't make a bug.
Which is weird for me to say, because I'm the one who originally reported the issue. As a bug

Can look up the thread if you're interested. Happened in 1.21 or immediately afterwards. Should be somewhere in the bug section of the board.
There's tons of exploits related to having your capital in the new world and all of those exploits are 100% WAD.

Easily one of the most ridiculous things I've ever been told by someone working on the team, if not the most ridiculous thing.
"I can see how you're exploiting the crap out of it. That's exactly how we wanted it to be and it won't get changed."

Not using those exact words ofc.

"I can see how you're exploiting the crap out of it. That's exactly how we wanted it to be and it won't get changed."

Seriously? That makes being a coloniser almost a punishment for all the money and resources you put into the CN to than let them mess up everything. Well I'll remember that when I want to do another exodus run .

 

[Zohtun]

I know that Hungary gets a decision to just submit to Austria in an event (specifically when their Habsberg kid becomes ruler), so maybe they took that one and resulted in Austria-Hungary PU while also at war with Ottomans.

 

[Popenomore]

Hungary was already under the pu before he declared war and had been for a long time

What happens? I'd guess that the Castile-Austria war would just get cancelled.

If they are separately at war - it gets cancelled since France is already at war with Austria.
If not:
if Castile was attacker or an ally called in by the primary defender, it stops being a participant, leaving its allies to fight Austria.
if Castile was primary defender, France becomes primary defender in their place.

A nation at war cannot fall into PU naturally.

It's Hungary and Austria, there's an event chain. I don't know if war stops it though.

See bolded part.

imo it's more thing for more babysitting and don't exploit them too hard.

In case you do one, do me a solid and check if annexing provinces still causes global AE.

That bug was hilarious in combination with the tributary AE exploit. Got a screenshot somewhere of over 50 nations declaring a punitive war on Ming

don't exploit them too hard.

Oh I would never



Sidenote, with a title like that I totally expected someone to have figured out how the free PU exploit works.
Hint: Pretender rebels

 

[Popenomore]

Hungary is still in the pu and at war with poland at the same time and was not at war prior

 

[Tarkilth]

Falling into a union while the war is going on could possibly explain one occurence, but if we are to take OP at their word, if it was a repeat happening (three times) then I can't think of anything but shady things.
