Just disable automation on those fleets with postures and everything will be fine.^^
The manual says: "Fleet postures allow the player a middle ground between full automation
and manual control."
And that's the way it is.

I had the same problem with that funny (old & new) race_16 file and finaly replaced it as DownTheDrain said.
Now a picture of Brad Pit represents the Ferengi... [8D]

Many thanks for that cool mod!
