WaterlooJL Activity

I was able to get it to work.  I got to it from this video. Did you also install a League Results mod (linked in the video)?  Following the instructions I was able to start with Leeds on June 5, 2023 and Leeds was sitting at 19th in the Prem tab...

Out of curiosity, why did you ask about Leeds?  If anything I'd suspect Palace, since the game sequences on the show are filmed at Palace's home ground (Selhurst Park).
