So I was showing someone my builds and when I loaded one of my saves, it automatically did a timelapse of the build - Like, it was an empty world then it just started building everything that I had done. It was really cool, and I was wondering if they was a feature or just a fluke? I would love to have this as an option but I cannot figure out how it happened as when I load my other saves they are just as normal from where I left off. Please help, thank you.
