Changing City's Names ?????

[d'Arthez]

Changing names of settlements may result in:
-issues with traits and ancilliaries
-issues with reforms
-issues with provinces that have scripted events, or are tied to factions (for instance Messana and Punic Wars, Byzantion, Halikarnassos etc.)
-issues with AI population replenishment. Have fun against an AI that depopulates all its cities
-government buildings (AI needs the assistance)
-victory conditions

In short the game will be a cakewalk.
