[32]Italy Non EU player rules
Many users start a save and are unaware of this rule
so you can use FMRTE to add a second nationality to a player etc but it wont change this rule
and so you are left being unable to register a player/s even if you have freed up a space
I suggest trying this
change those numbers here as a test I did this
you also need to remove this specific rule
I also added this but IMO it is unnecessary
Now in game note how the transfer rules has changed
all those complex rules are gone
Above was just an example of what can be changed[and you may have to do all of the above to get the desired change in game]
Give it a go but NB you need to do this for every comp you want to use in Italy
IMO just changing this rule/just unticking the Italian specific rule should be enough.
