Vassal AI weirdness

[MattStriker]

So in my current game I've managed to vassalize two AI players fairly early on, and they've been reasonably useful in the time since.

Now I'm in the endgame, I'm halfway through my doomsday (set to slow) so all players except for my two vassals are of course at war with me.

I'm beating the crap out of two of them simultaneously, rolling up city after city with 10+ armor doomstacks (Dvar Promethean is kinda hilariously broken if you find a city location with a promethean landmark :P), and my vassals are helping out a little as well, sniping a sector here and there...

...until the two AIs I'm fighting suddenly decide they can't keep going, and basically surrender...to my vassals. Each went to one of my vassals and offered to be vassalized by them in turn.

Which...okay, that could be nice, except that this didn't put them into an alliance with me, and because of their new alliance with very powerful players they were unwilling to make peace with me now. And of course the next turn, my vassals suddenly remembered they were supposed to be fighting everybody who is fighting me and declared war on them again...

Hey Matt, that sounds interesting to say the least. If you still have the save file please send it to us at [e-mail]. It'd be great if you could get us the save from before and after this occurred. Then we'll have a look to see what the AI is planning and why.

[MattStriker]

Unfortunately I didn't think of making a save for this.

Update: It happened again, sent the saves.

sounds for me like standard AOW AI behaviour, like the jokes they do by standard "hey fight this guy" next turn "hey i made peace with that guy, but you must still fight with him because now he dont likes you"

I got one for ya. Admittedly this was dumb on my part, but never make a defensive pact with a treacherous AI personality.

If they get attacked and ask for your help, they will lower their opinion of you after you do exactly what they asked. "Hey, I noticed you're at war with someone new and now I dislike you more because you're in a weaker position, given you've just entered a new war".

Yeah, AI personalities have led to some added diplomacy silliness on top of the already existing mess.

Loyal AI ally wanting you to go to war with an AI you have a treaty with. Refuse? You lose the alliance, AI hates you for breaking the alliance. Go to war? The AI hates you now for breaking the treaty that it demanded you break just a turn ago.

Got it with the new AI perks that a AI that max liked me (same race, liked my race monothism) and i got a defense pact with made this:
demmanding help in a war, i accepted.
next turn: i dont like your performance so i end the defense pact with you.
turn after that: you do great, lets make a defense pact

Thanks Matt, we've received the saves and I passed them on to our Diplomacy guy.

Furthermore, if you guys ever encounter behaviour where the AI doesn't act in accordance with your expectations just reach out to us. Make a bug report on the forums or sent us a email with a description and before/after saves and we'll have a look at the AI planning.
