I used to download a free world template called "Grid Runner" in the marketplace, and created the world. Later, I deleted the world because of too many files, but the template is still retained. Later, the template has been updated, and the market shows "downloading", but it isn’t downloading in reality.I deleted the World Template and plan to download it again, but I still can’t download it after deleting it. Is this a bug? How to deal with it?
