Are your rules correct in Austria? The game says that in match squad I can have only 3 foreigners, but in real matches there are more of them.

I found another bug. I'm playing AS Magenta, New Caledonia and I can't choose any player to OFC Champions League match! No one is registered, but there is no option to register them.
It's a bug in French Cup. When I play AS Dragon from Tahiti, I can choose only 4 of my players because all of them are counted as "Foreign - Non EU Player". Although they have French and Tahitien citizenship.
