now the physical preparation course no longer earns training points for training clubs like me, so the +1 bonus is no longer counted, which is great...

Unfortunately, that's the way it is.
You can always ask the lending club(s) to compensate you for the loss of earnings?

It's totally unfair that players who have been on training loan for more than 56 days don't get any points. What's more, we no longer have the option of recalling our youngsters or even having them cancelled by an administrator. 😮‍💨
