A Question About Anger

[DirectorTsaarx]

Usually you get a message about a communications mimic being used against you; generally at the same time as you get the message declaring war...

You say you had a partnership with Eee and Xiati? Which means that when you entered Sergetti space, they could see the same Sergetti sectors you saw; maybe they got angry about those? Or maybe they had (or entered into) treaties with Sergetti, and decided to turn against you.

As for the EA, they may just be predisposed to dislike other races. Some races are like that; I had to toast the Abbidon in my most recent game, because they refused to make treaties & then started attacking my planets. Very un-neighborly.

Sounds like the Sergetti may of had treaties with the Earth Alliance and the Xiati and maybe the Eee and called on them to attack your empire. A partnership with either the Xiati or the Eee with whom you had a partnership would have given all the information about your systems to the Earth Alliance who used this information. It would seem that your attempting to push the Segetti around lead to your being stabbed in the back politically.

I'm not too sure that there isn't some plain old RANDOMNESS built into the AI reactions. Notice the "Propose Treaty Percent Chance Per Turn" setting in the AI_Politics files. So this is randomized even when under control of anger levels. There might be some random factors involving 'first impressions' and reactions to events, as well. I've been at "Moderate" with some AIs and had them declare war the very next turn even though I saw no events in the log about any conflict that could have set them off.
