I'll explain steps for copying my OF so you'll better undertstand:
-1st Step: Since i've make copy of many players before the 2.00 DLC, i've got a big database if i want to re-basecopy... And that's what i've done them every free and fake players unused in my option file. Then i've make a transfers reset and then exports all teams data.
So you'll have to import all data at first, for having those player's.
-2nd Step: Now, we really are importing the teams data/transfers.
The system from the 1st step will allow all real players removed i've basecopied example for Bayern, Copenhagen, Galatasaray etc. to go on "free agent".
So the issue with the fake players in ML is gone.
-3rd Step: For every club with real players, it's better not touching the players and formations, but only graphics and club informations: I make this for having a better compatibility with the Live Update system.
So, don't check "Apply player and squad data" for those one.
All you'll have to do if you apply a Live update, is to re-import all fake leagues i've exported (2nd step)
I'll explain exactly what to do when i open the thread, it's not difficult to import, only explaining my work was a bit lol
Of course, with Winter transfers, it will be some update. But, i'm gonna get busy and also want to work on an accurate Fifa, or FM > PES converter
