Oy there.
I, too, have problems with those wretchs. i used tweakmb to change their party numbers and troop numbers, but neither of wich changed in-game. i even started a new game.
they're still everywhere and got 25+ troops even tought i made massive changes in their number and applied the changes.
Dunno what'odo. I'll keep tryin', but ill post this message Just'n'case.
