World deleted both of its copys of itself and a old copy of the world, which I deleted, reappered but won't load.

Me and my friend made a world on my Xbox one, the last time we got off of the world I made a copy because this isn't the first time a world deleted on my Xbox one. When I go to get back on both of the copys were deleted for some dumb reason, but an old copy which I deleted was back for some reason. I tried to load the old copy because it is better than nothing, but it wouldn't load. We have spent so much time on that world and I would really like it back, but base on many other expenses with stuff like this, I know its not going to happen. Im holding on to the old copys in hope that they will work and load some day.
