Game won't save on xbox one version of fs 2015

[Racing Chicken]

The other day I went on farming simulator and did quite a lot of work on there. I then went to save the game and all of a sudden the game shut down, I then went back into the game to find that the game hadn't saved and wasn't there at all. I have tried rebooting my console but still can't save anything.
Please help as I can't play my favourite game farming simulator anymore.
