what you mean?
its like a quit a different, if you talking about an Army (party) size or having 2k troops running over the battlefield. Also its important to know, how far your progress is. if you are at the end of a game, i would not say, this is a bug at all, but a little weird. Every game , every save, has its own algorithm. meaning, that , if you start a new game and have some progress, the game will be very different from the first one.
