Old Firm in the Premier League database 2504

Merry Christmas, everyone! This is my Christmas present, as well as a traditional database that I make every year: Old Firm in EPL. 
Just like the title, it moved both Celtic and Rangers to the Premier League, as well as their B teams to England, while other teams were promoted/relegated accordingly.

Instructions:

Android: 
- Extract the .zip file, then put the db_archive_2405 folder in Android\data\com.netflix.NGP.FootballManagerMobile\files\Documents. Create folders if they don't exist, and replace any files there if needed.
- Open the game, choose Settings - User Interface - Reload Skin. Then choose New Game.
A third-party files explorer, such as MiXplorer or Total Commander, is recommended for Android 11+. You can use PC to copy these files as a last resort
