[Signing NewGen players at other clubs]

Just a note that if you want SI to review this potential issue, please describe the issue and provide a save game that enables them to reproduce it. It's difficult to review anything without it.

It doesn't seem common for under 18 players to move (though not saying there aren't examples) when they're potentially a year or two away from even having a professional contract. As SI indicated specifically above - players with less than a year left should be looking to move and so should be open to negotiating with you.

How do I even add a save file so big?
