I can't save the story corretly

Hi all,
I can't the story correctly.
When I load the story that I saved before, I always go to the end of the story.
I have updated the version of ink.
Someone can help me?

Start in the GameState.Enter method and trace the inkSaveState load path alongside saveStory and OnAdvanceStory. Reproduce loading a saved story, then verify that the Ink story state is initialized and restored correctly before the story advances; done means reopening a saved story resumes at its saved position.
