in a directory called "Italica_Campaign"
but for strange reason it says it can't find the region names.Ot's strange because it seems like it can't read the file in the text directory cause if i put those lines in the imperial_campiagn one(the file in in text directory) it works i have tried to move the regions to see if it was a specific one but it says always the same
