I seemed to have lost Ryan Giggs in my first team, so i quick searched for him, found him - and he was in my first team but i could see him there... so i moved him to the reserves and i can see him there! move him back to first team and he's gone again!
then if i use the filter to show the reserves in the first team window... he's gone!
