A new upload has been made for Knight of the Blue Surcoate. All things considered, this wasn't a very disappointing bug. Once you beat the end boss, you should just be able to keep exploring until you're ready to go through the last doors in the Netherworld castle, finding the secrets of the game. Unfortunately, what this bug did is this; you could really only explore the Netherworld, which is just two maps. Once you leave, the bug triggers the ending automatically. Like I said, it's not a serious bug. It prematurely triggers the ending AFTER the end boss and slightly messes up character positioning and BGM. It doesn't really break anything major, but it will prevent you from finding game secrets.
