Odd. I did pretty extensive testing with them in the past and they move out rapidly and effectively. But it's been a while, I suppose.
Won't have a chance to crack open the save until later, but just checking: is it before the first imperial spawn or after? One of both is preferable, but the one from before the spawn is most important for debugging.
Edit: btw, what it does is:
- spawn a BB-led fleet to cover your homeworld (for each homeworld, if more than one, iirc)
- spawn a BB-led fleet to cover each spire city on the map
- spawn a SD-led fleet to bumrush each AI homeworld
- spawn a number of DN-led fleets (and more over time), each of which basically says "if I'm not currently killing an AI planet, find the nearest one that isn't already accounted for and go kill it"
So if there's a lot of them it may look more disorganized than it is. It's also possible that logic is borked, too, but it used to work
