Update 23.3.0 really messed up the fun in the editor... Before I made a lot of different nations which were playable along each other. But now that the Nations League teams are seeded, the Nations League will miss a whole division when you remove a team...
At first I thought I did something wrong, but I read a lot of fellow players experience the same problems.
At the moment I'm trying to make a file I break up Spain in (Spain, Basque Country, Catalonia, Balearic Islands, Canary Islands ( Ceuta&Melilla, Menorca))
and later try an expanded Great Britain file... But at the moment it's useless because even the single saves aren't complete while do not particiapte in the Nations League and EC qualifiers... I don't even dare to update my current countries
If anyone knows an easy and safe solution, or has an good working expanded Europe Pack ( around 60 70 or 80 countries instead 54 ) please let me know
