Description
Vassalization of an empire at war ends the war and closes borders (3.4.3 9d15)

Game Version
Cepheus 3.4.3 9d15

What version do you use?
Steam

What expansions do you have installed?


Do you have mods enabled?
Yes

Please explain your issue is in as much detail as possible.
the AI empire to my galactic south declared war on me. Through the course of the war I took full control of a number of systems that I had made claims to. Suddenly, my fleets were ejected from the systems I had control of and sent into emergency return. All systems returned to the other empires control. Upon investigation (using observe mode), the empire I was at war with had become a subsidiary to another AI empire during the war.

Mods are tinyoutliner and a custom starting system. Reran the saves with no mods. AI empire was still able to be vassalized causing the war to end with no loss for them.

Steps to reproduce the issue.
Run autosave_2287.01.01 at some point in the next 6 months the AI empire will get vassalized and the war will end with all controlled claims being reverted and fleets being sent to MIA due to border closure

I'm not the only one to have had this occur

interesting report w/ save

I wonder if this also happens when you're the aggressor instead of defender in a war.

could possibly be working "as designed" but... worth debating if it should be designed that way

I would consider working as designed if they intended for vassalization to be permitted when empires are at war. Considering that this is not possible for players tells me otherwise.
