When I train new Administrators, I get the admin points as expected, but I can only train 10 of them. From everything I've read, I should be able to train as many as i want. When I select Administration, the Train button grays out, and the hover message says I need to assign some Administrators to planets. But the Transfer button is disabled whenever I train Admins, and if I go to a planet and try to assign from there, only non Admin Citizens are selectable. How do you get past this?
