Thanks for taking a look. I couldn't figure it out, so I started over with trying to create a brand new US system, and I have issues there too lol. Basically it's a 4 level structure with 20 teams each and 3 pro/rel spots for each division (top division only relegates and bottom only promotes, obviously). My top division verifies in the advanced rules, but my bottom 3 do not. I get an error:
"Wrong number of teams (XX) found for stage 0 of United States Championship (20 required)"
The funny thing is that the XX number varies each individual time I run the rules. It's sometimes 17, 18, or 19. I think it has something to do with the pro/rel not happening correctly, but I'm not sure. The database verifies with basic rules, but the moment I turn on advanced rules I get this error.
Edit: This is using the FM22 editor, so the database is 22.4
