Hello, I am struggling to find a way to merge/import downloaded nation rules into my own edited editor data. The nation rules was made last year and used 23.0.0 database.- I tried to merge directly both of them but the nation rules did no merged into my own data as I tried by creating a new game with the nation still has the original nation rules but my own data is normal. - I tried to export the downloaded data then merged it with my own data but when I tried it, the players and staff that I added in my own editor data lost all their pictures and possibly it used older database even though I picked the latest database when I create a new game. Is there any better way to do this? Currently I'm trying to just edit my own data and copy all the nation rules manually. Thank you for your help.
