The Fornite Fracture is growing, and there is proof. On June 29th a missile flew around the map and put a fracture in the sky.

We are anticipating that once season 4 ends, the map will changed and obviously it has something to do with the fracture. Check out the proof that the fracture is growing in the image below.
