The game sets the year back to 1974, to make the player have a somewhat realistic age for a manager. It doesn't do this if you're born before a certain date. Don't know what that date is exactly.

The editor to use would be MCFM, but the current version doesn't allow the player's character to be edited yet. Players and staff have priority for the MindCompression guys, unless they stumble across this while doing other stuff.

Didnt it used to make your age something like a minimum of 45 in previous versions until Chris Coleman emerged on the scene?
