I don't have access to Fortnite Save the World anymore?

I recently redownloaded fortnite and was excited to play the new season with the OG map and was also excited to go back to save the world. When I clicked on save the world, it said that I didn't have it and that I'd either have to put in a code for one or buy a bundle that came with it. Even if you do not believe me, there are multiple achievements from save the world that were only last year. I am indeed signed in on the correct account, so it isn't that. Can someone please help me out with this issue? Thanks. (Note: My username is if your like to check)
