I downloaded and fixed up regional rules for an Australian file which hadn't done them correctly, however, when I load this specific file with multiple other files, regional divisions are ignored and teams just randomly just transfer between different leagues within the same parent comp, despite being set to a specific competition. What changes can I make to the file to fix this.
Please do not respond with "don't load multiple files." If I didn't want to work out another solution, I wouldn't have made this post.
