Sorry, I don't really play Stellaris anymore.

The problem you speak of though is due to being allianced and them having a higher claim on the system.

If you want it to be yours, you need to have a higher claim, or equal claim. (Equal claim will do what you said. Whoever gets there first wins).

Could you do a fix for Conquer as well. Here is the problem in 2.8:
I claim all my enemies systems. But another empire has claimed some of them as well with intent to go to war. But I get there first and wipe out my enemy. But the other empire (who is NOT an ally or a in a federation with me, and did not fight at all), gets my system I just fought for. I even fight the ground war. So why should an AI be able to take an enemies planet after YOU fight for it?Then at the end when I tried to get him to surrender to conquer it said -3000 for trying to claim planets I did not occupy. FIX: I think if you fight for a planet and win, then YOU should get to claim that planet/system (Like the synth option) If the other empire has a claim on it but does NOT fight for it then they should not get it. Can you make a fix like that? I love making huge fleets and storming the galaxy. But its not fun when you do all that work and the other wimpy race claims half your spoils for doing nothing.

Ayy don't shoot the messenger

Could you make one for tributaries? They are also broken with the negative modifiers.
RIght now the domination tree and playstyle is completly useless.

@Sou

This doesn't fix that. I am not sure how too.

This is what ThePionier was talking about https://gyazo.com/341ebcd42fc3c626afc5aa4a4c0dc658

Nobody is at war though

@k4nd17r33

Yea I did. The problem unfortunately is due to how everything is setup. Their logic works technically.. but doesn't at athe same time. Its working as intended, but creates problems like my example above, espcially with the new hyperlane only change.

Did you make a post on the Paradox forums? Looks like something the dev team can easily fix! Good for you to make a bugfixing mod though :)

I think you can script more specific conditions to end war instead of simple warscore adjustments, and without overriding files like current version does.
For example, add yearly event to check if -- a) all future-vassal (using_war_goal) planets were occupied - b) claims on its allies occupied too - c) def_war_exhaustion_sum >>> off_war_exhaustion_sum or major attacker fleet superiority -- and if so, have defenders concede.

Static bonus/penalty due to wargoal doesn't seem to take many things into account, as indeed having allies fight Total War for some tiny vassal when there are no claims on them and little chance to win seem to be kinda broken.

No, unfortunately not. That was in my last game.

Do you have a screenshot?

That could be possible with the -50, then Paradox could have described it a little better.
I read from it that he is still at war with me, even though I won the war.

@ ThePionier

I can look into this, but I think the permenant -50 is due to being a vassal no? I think its intended to show that nobody really likes being under someones boot permenantly, empires, like people like to be free and under their own control.

Yes, he had a permanent opinion from -50 In War.
I won the war and he became my vassal.

@ThePionier

I'm sorry I'm not entirely sure what you mean exactly. Can you clarify?

Do you mean his opinion of you?

Hi
I recently had the problem when I vassalize another empire, which I lasts a -50 penalty in war on this empire. Is this problem also fixed?
