I'm in the process of adding in lists of city names for all my civs in my personal mod. Two nations ended up with the same city name and I left it that way to see what would happen. While playtesting I noticed the 1st civ used the city name and then when the 2nd civ came across that same city name, it skipped it and went to the next name in its list. Is this all that will happen in this situation and therefore there is nothing to worry about, or is there some error that would eventually pop up?
