Xbox Players Save File

I’ve done about 8 missions and my game crashed when I tried to return to Headquarters…loaded up the game and it’s like starting fresh as it tells me about the game and having to hold A then I’m in Headquarters and there’s only the first mission available to me…it’s not saved all 8 missions in my campaign mode so watch and check it saves your game

Has anyone else on Xbox experienced this happening ?

I’m so mad as I’ve been at it 7 hours so far 😂
