Dynasty Schedule and Conference Issues

The issue: after season 2 we took odu out of the sun belt and moved them to the ACC. A user left Coastal for Baylor, another stayed at Marshall. This was where the first issue in the conferences occurred, the sun belt conference games weren’t counting as conference games in season 3, but it didn’t matter because aidan was at baseball, so I let it go for a season. When the Marshall user came back for season 4, I was making sure aidan was going to get a conference game, but the sun belt settings weren’t even letting me turn on championship for the conference. So I quarantined the conference and put Marshall independent. Season 5 rolled around and I was trying to get them back into a conference, and the sun belt was available for a championship again so I thought the issue was fixed, didn’t touch the conference, and I put marshall in the Pac12, and moved of the old Pac12 teams back there so aidan had a competitive conference. I simmed thinking all was well, and when I went to make a custom schedule, no matter what I did, it said invalid schedule, invalid teams. No matter what I do now, I can’t change the schedules going forward. I went on Reddit and put it into 2 different subreddits and everyone says it never goes back to normal.
