Your Creative 1.0 island got archived and now it is gone, even after recovering it? Here’s how I fixed it:
1 - Access UEFN Content Service and log in. ((UEFN - Content Service))
2 - Go to Fortnite Creator Portal and make a new Team ((https://create.fortnite.com))
3 - At Content Service, go to “My Teams” and copy the code below the team name you just created.
(I made a random one in the photo)
4 - Select your project on Content Service and select “Transfer Project”
5 - Paste the team code you copied previously and confirm the project transference.
6 -Your island should now appear again in your creative console!
