Me and my cousin were playing when I accidentally without looking at my controller, deleted the world, we were really good and now we’re both pretty sad that all our work is lost and we have no motivation to make a new world
That's too bad but I encourage you and your friend to try starting again. The first few days are quite a bit of fun as you seek a preliminary base and get established. Before long both of you will be engrossed in a new world again.
There won't be any changes to the game on console. What's done is done.
