Someone in this thread posted that F! would not be shown on most weeknights during October because that's what usually happens.

You were given the correct information. We only have what has happened in the past to inform us of what might happen in the future. However, things can always change, unexpectedly. Disney could always decide to add in some random weeknights for F! out of the blue, surprising all of us. It sounds like the weeknight thing is a mistake this time around, but it could always happen. It's just that it's not what usually happens, and that's all we have to go by.
I understand that yes, it is based on what has happened in past years. And the way things are going this year, apparently almost nothing is the same as the years prior so I should have known
.
Thank you (and Geemo, too!) for letting us know about this. I thought it seemed odd that Disney was going to add in some F! weeknights, but then I just assumed that maybe they were doing it because there are so many MHP nights this time around, and a lot of interruptions to the F! schedule.
I should have known that it was yet another mistake! You're right -- the whole scheduling/calendar/reservations issues is crazy this year. I have no idea what's going on over at DLR. And the whole situation with people ordering and receiving their MHP tickets was crazy for a while too, with some people receiving no tickets, or receiving the incorrect tickets, or getting an extra receipt but no tickets!
