I made a lot of changes to the 32 WC squads, making all formations and lineups accurate to WC22 stats.Describe exactly what needs to be improved
As it turns out, adding a specific formation to Brazil was a mistake, because that broke the formations ingame for Brazil, Spain (and maybe other teams, I haven't checked all).
Then I removed the specific Brazil formation and even had to remove the specific Spain formation.
I can only hope that all the other teams (and everything else) are ok now.
Another solution I might see with this if some bugs occur is taking my WC22 DB and importing to it the "default" FNT 5.0.0. formations table.
