A friend and I where playing on the PC here some informations about the save.
- I train Lazio and my friend trains Cagliari
- My friend wanted to loan Martin Baturina. He selects the player and sends the loan request. The loan request can be found at Cagliaris Club as "Incoming Transfers".
- Then I press "next day" in order to progress the game.
- Now me as Lazio Manager will never get the Transfer request.
- The request made by my friend at Cagliari disappears from "Transfers".
Basically, Loan Transfers among human players do not work. I needed to do this Transfer via inGame Editor.
