About the hair, I sincerely have no idea, most hair files work normally (even those from Nintendo Switch converted to FIFA 14), however I have seen a few which cause issues for some reason, but at the moment I have no idea.
About adding Feyenoord or other teams, it is possible to add more teams to the database. In fact, as I already pointed out before, all the leagues/teams that were in FIFA 11/12 have their kits already in the game. Most of them are from the 2011 season, but they are already there. You only need to add the leagueids in the database, add the teams in the database and add the players. You don't even need to mess with the .big files, everything can be done externally if you use my revolution mod.
Ok sounds great but can you maybe tell me how to add teams externally because i only know how to add faces.
thank you in advance,
