And fanon is fine for custom ordering if you're just playing files in VLC. But if you're using an organiser, you're gonna have to comply whatever metadata that organiser pulls from or weird shit will happen. Pretty much just episodes being numbered with no names, no cast/crew list, generic date (1/1/1970), and an ugly thumbnail for the episode preview. Which all defeats the purpose of using the organiser. The point being, for it to look pretty on your TV or mobile device.

With Jellyfin, you can pretty much force it to go the way you want, though. Just match everything and then manually enter all the data. You can force Jellyfin. Plex on the other hand...
