When there should be 2 overworld surfaces when there should be only 1 caves and 1 overworl. This is not normal and one time on a deleted world the world would not rollback ingame when we could have only rollbacked in the rollback screen when we would startt he world being a major inconvience
Steps to Reproduce
I have no idea to be honest it just happened.
This issue has not been confirmed by a developer yet.
