Ahhh alright I think I found the cause of this -- I adjusted some of the stats on the original one and it seems you can't adjust the year date in which the players became pro because it contracts with their preset year end rankings. But yeah its weird it worked even I had that pro year changed for that character -- except the appearance of the racquet was missing -- i couldn't find the issue for that so i just left it. then like a few days later then invalid came up. But yeah, its ok now!! So yeah warning to all people i guess --- dont change the "FirstYear" Stat!!!
Moral of the story -- experiment some more before blindly asking why something doesn't work
