I noticed this a week ago, as well. The scheduling changed for FSU. There is a list of conference opponents for each team, but there are no dates set for any conference game in 2023.
I was planning to go to the FSU @ Pitt game in 2024, but I see that game has been moved up to 2023. I am hoping I can make it. I wish they would set the 2023 ACC conference game schedules, so I can reserve that weekend before it is taken up by work.
