Why are my worlds gone?

I made a new character and world after the update because I could not access my old world. I started playing for a while and then I heard that camp fires were the reason why my old worlds were showing failed loading messages. I was going to try deleting
the update and removing the campfires in my old world. Now all my character profiles are gone and I still can't access my old worlds.

It was good knowing you terraria

I did it. But my world is still gone

Your World was saved in your hard disk console? You take the restore from old backup?

Try to Sync your data to do so clearing your reserved space, once u log in the game it should try to sync yo data

I own the digital copy of minecraft if thats what your asking i dont really know what your asking
