There will be a gallery when you complete the game to view missed scenes. You can also revert to a previous save if you need to.
Does the current version no longer disappear on its own?
I don't quite understand your question.
The large enemy in the cave shouldn't disappear on its own. You will be able to discover him if you simply walk to the area where he is... maybe you can see his shadow?
Sorry.
I may have looked at it wrong.
I will try again with another saved data!
