I am playing on 8.02 updated version (FMM 2.25) - ofc my game is original, but I installed some patch that swapped Italian and Polish league, so I (as a Pole) could play my favourite team starting from some bottom league (4th). But unfortunately this patch, together with swapping leagues also swapped restrictions - in Poland you could sign as many foreigners, as you just want to - in Italy only 1 per year. So what I am doing is to change countries status to - Member of EU, so I could sign players from those nations freely.
But I am able to do that only with african countries - cause Modifier does not seem to recognize countries like Brazil, Argentina, all - EU countries except Luxembourg, Serbia, Ukraine and so on. When I go to player profile on FM Modifier in the row 'nationality' there is empty non-editable space as if his country did not exist. And when I change nationality of some player whose previous nationality is available in FM Modifier - some Ghanian man for instance - there is a huge number of countries where it is written 'Can't Read'. You know - I click on his ghanian nationality in modifier in order to change it, and whole list opens eg. - Aruba (..) Belize (..) Cambodia, Can't read, Can't read (like 60 or more times) and then Dominicana and other minor countries up to Z.

What it may be and how to fix it - I'd love to see a hint - cause it would bring my game again back to reality.

Cheers
