you can import new name file from different thread

one catch is the current names on players are to still be used but later on you may or may not see new names entering game. For me i think i did it wrong but the updated names seem to work better when you restart game from the current version. As back years ago i wanted certain names entering game but i actially think i did it wrong. Possible i did it right i just didnt see. Nobodies fault but my own.
Good luck and perhaps there are better ways to handle this today. Never asked recently as in OOTP23 i am starting my 4th solo so all this is moot to me now
