I try to change a dlc lua file to improve the peasont economy behaviour, but when including the file into the pack file, the game does not display correctly its ui bar. I seem to do something wrong and cannot find any help or information on any of the modding forums, your help would be appreciated.

What I have done is add a file from pack, got the file from warhammer data and then edited it.
Saved the pack file and added it to my mods folder, aka data in warhammer II
Everything loads, but the campaign UI top bar that shows peasant level etc, does not work anymore

It seems that the file conflicts somehow, but I cannot figure out what I need to do to make my file work.

If you could be so kind and point me in the right direction or where I could learn about that maybe.

I searched everywhere, but beside some excellent info from Magnar I could not find anything regarding scripting in Warhammer.
