It sounds like you died while beating the boss, if you were teleported to the last save? If so, the game hasn't saved after you beat the boss, and the game still doesn't "know" that you've beaten the boss. Whatever happened, if you were teleported to a save that you made before beating the boss, the game wouldn't register that the boss has been beaten 🤔 if you beat the boss, the game should let you walk back to the coffin, (with different music and no enemies now) which should display a message saying that you can rest. Idk, maybe I'm still not understanding you right, but it sounds weird - I'll try looking into it at some point 😄
