I have heard of this before but I hadn't really encountered it until this game

http://warlight.net/MultiPlayer?GameID=5851980

turn 13 the ai looks like it judged the opponent to be to much of a threat and retreated into my unprotected bonus.

not really a big deal as I am still tweaking the settings on that map and get a sense of balance which it's still quite not there yet, but I digress.

Anyone know the cause for this?

The AI may attack teammates only if it can complete a bonus because of it.

Since apparently on this map every triangle is a bonus, it only needed this one territory to complete it and hence it was an option to attack it. It has a random component, so sometimes this will happen, sometimes not.

More precisely: The AI may attack teammates only if it can complete a bonus or a superbonus because of it, no matter if the teammate thus might lose a bonus.

I ll be probably asked for a game link:

Turn 19 and later in Gallia.

IIRC AI's attack to take a bonus from allies if...

1) There's no hostiles in the bonus
2) They have over 50% of the bonus
3) All allied territories have 1 army (?)

Behaviour of the AI in team games

It will only attack teammates in two circumstances:
If a bonus is entirely controlled by teammates and it has >= 50% of the territories. It will only do attacks of 2 then.
If it's expanding into a new bonus that no teammates control. [9]

well that seems to explain it. Also especially the smaller 1 bonuses on that map.

Well Lesson learned F the AI lol

When the AI began to take Gallia superbonus in the game i linked above, it held 15 of Gallias territories, tm Harkonnen and me together 16 (3+13). Maybe if the AI holds the major share of territories in a superbonus all controlled by allies, then it begins taking it.

Luckily, you can see the AIs orders and counter them easily (I have had to do this a couple times). I also like the map you were playing on (:
