I edited the customregions.xml file and removed some stuff (RHPD, DPPD, LSIAP etc.), I also changed some vehicles that respond in certain areas, but when I entered the game nothing changed, I checked that I saved the changes and everything and, for example RHPD is still in their designated area even though I removed them. Also in the defaultregions.xml file there are like 5 San andreas highway patrol parts, and they are all identical, so if I wanted to modify them I don't know which one I should modify.
