The map now uses Taleworlds' alternate display mode for factions without faction colors, where faction and friend or foe status of a town, castle or village is displayed when you place the mouse cursor over it. This mode enhances the meaning of the banners flown over castles and cities: As in medieval heraldry, the identity of the individual noble comes into the foreground. Know his or her coat of arms and you will know what faction the respective place belongs to.
You will find that this more historical map mode doesn't take much time to get used to. If you wish to change back to the classic mode, go to the module.ini file in the mod's folder and look for the following entry at the bottom:
show_faction_color = 0
Change it to "1".
