You caught a bug. I don't know what caused it, but at the moment there are only 2 epilogues in the game for Harold and Spencer, and a new 3rd epilogue for Chester recently has been released. It is currently available only on patron, but should appear in the itch.io version a little later. Also, the version for patreon supporters, has an exclusive bonus episode for Spencer related to Azaghal. All epilogues and episodes become available only after completion of the character's route with the best ending.
