Yes, because the teams database inside your patch is much better, have better formation than in fip v4.1 for example who did see England with formation 5-3-2? Anch such it is in FIP v4.1 So I move only players. However after more debugging I noticed that the stats of most players are exactly the same in your patch and FIPv4.1 none any difference or ther are differences that level of player differ about 2-3 points only. Also pics and heads very often are different. So it is not worth to update such existing players, I will only import to your patch players who don't exist in your patch and then update those ones whose I noticed that level is much different like Maitland-Niles from England. In your patch it has level about 60 in FIPv4.1 about 75. In Austria team I also noticed 3-4 players with big level difference. So hope there won't be any issue with such small update.Your cmp file only adds players to the database, but does not add them to the team, so it misses the point.
