I seem to keep having an issue where I'll offer young players out on loan, receive rubbish bids which I reject, then the player complains about me blocking the loan (almost as if it was a full transfer) and then asks to leave permanently. It seems like a glitch that they ask for a full transfer? Annoyingly they don't ever listen if I say they won't get much playing time, despite the fact the loan deal offered was for a Backup!
