Having actually beat the challenge two years running (in season 20 in both FM21 and 22, coincidentally), I'm not entirely sure I will be running it again this year. But, I have started holidaying and building up a save database, just in case. So, as in previous years, I will again host those saves on my mediafire account for those who want to save time and dive in.
Note: These are what I have obtained so far, but are not actually uploaded yet. I'll get to that this weekend --- so far, I have one half of the available teams, and will continue over the next week or so to find more.
PS -- if you find a save you like but with a setup you don't (too many players for your machine to handle, too few players to your liking), you can download the savefile and Add/Edit league (from the main menu) to add new leagues, make leagues playable that are view only, or make them view only if they are set to playable. This will tailor the size/speed of the sim to your liking).
