Sea of thieves?

I bought the game sea of thieves yesterday and then started the maiden voyage after 4 hours I went to bed I turned off the xbox and this morning I wanted to continue with the maiden voyage but it started again from the beginning how can I go back to the other stood up?

If you don't have to finish the missions first, the game saves

Does not go you have to finish missions only then is saved.

What kind of missions? In the maiden voyage?

I mean the maiden voyage.
