I havent played Advent on Culture tech for a long time, but with Rebellion i gave it a new try.
I can remember that my Culture could turn Pirate Bases to Neutral, i dont know in wich expansion or mod this was, but it was possible if i remember correctly.
Now i tried it again, but the Pirate base was remaining at 25% Allegiance.
So i have only a small question:
Is it possible to "destroy" Neutral faction planets with Advent Culture?
