I preface this with an apology; I'm extremely new to modding/editing the Total War series, so I'm sorry if this question comes across as really stupid.

I, as many others have found, have had issues with squalor and hunger once provinces and settlements get larger. I'd like to edit certain building stats/modifiers to alleviate this issue; for example, instead of the Suebi "Holy Tree" giving +2 Public Order, modify that particular building to provide +5 public order. I've downloaded the PFM and EditSF tools, and I've opened up the respective files (packs/save game), but there's so much information it's mind-boggling.

Can anyone more experienced in modding give a brief explanation about where to find the parameters I'd need to edit to have the above effect?

Thanks in advance.
