Confirm that the strings are located in the wrong place currently, should be moved to civ files.
Confirm the strings are extracted correctly and that duplicate strings dont pose any problems.
If there is someone who wants to do the historic accuracy part, they can do so without any additional cost (time cost for developers or translators) in a separate patch, or here.
Consider updating https://trac.wildfiregames.com/wiki/Mod_Layout#civs
Notice that the game now choses unique names in all cases for the current max playercount and civ files.
Notice that if one removes the names of a civ below the chosen AI playercount of that civ, it will deduplicate.
For example remove all names in rome.json but one to see the deduplication in process.
