Actually that party showed up after I thought I had changed the maximum party size to 150 so that is why I think/know I obviously did something wrong.
What I want to do now, is prevent any more groups getting this big so that is why I need someone to explain to me what I am doing wrong.
I basically went to TweakMB -> Parties (Size and Moral) -> Bandit Party Sizes
Then I changed the max value to the total amount I thought should be in a party. For example I have set the parameters for Manhunters (troop 1) - pt_manhunters_e min 18 max 40 which I took as meaning the bands would have a minimum of 18 troops and a maxium of 40. I then saved the file and started M&B. Then started a new game from scratch. Thought I was good until I saw the 198 member group which is obviously larger than the 150 Maximum I specified.
So what am I doing wrong?
It seems straight forward except for the verbage that I can set either values or percentages. Also I am wondering if like for player parties, the numbers I am setting are actually modifed by something hidden like a hidden leadership ability for the Bandit or Manhunter parties ie the Max setting being 40 is modifed by a party leadership of 6 so group size actually is 40x6= 240 rather than 40 total.
Anyway, I don't understand what I am doing wrong but if I have the max value at 150, I shouldn't be seeing 198 manhunters all in one group so it has to be my lack of understanding what exactly I am doing.
In any case, I am really wanting to play but don't want to progress any further if I am going to have bandits and manhunter parties getting 400-500 strong. Kind of a waste of my time to me anyway.
