Maybe but they still have Season ticket holders as far as I'm aware.
Tricky unless you've adjusted the database and made a mistake (something easily done) this is definately one for the bugs forums, I expect the Rule Groups folks may appreciate a screenshot or a saved game showing the club information page as well.
Don't even touch the editor mate, as it's wrong on so many levels!! (i just get tempted to make Nottm Forest a world super power and i think i'll just wait a couple of seasons so that it happens IRL!! ha)
Even stranger, i have another saved dutch game where the do have season ticket holders, it just seems to be when i take over for some reason!
Will do as you suggest and post a couple screen shots.
