I am not sure if the base game or an editor file that I am using did it, but my save's Serbian league has rules limiting teams to 4 non-EU players.
As Serbia is not an EU country this is obviously incorrect but I need a way to solve this issue.
Via the in-game editor is it possible to?
a) Fix the rule
b) Allow all teams to ignore the rule
c) Get around the rule by making Serbia an EU country or another similar solution?
