According to the recent data, there are cracks in the sky of Fortnite Items so long that it seems that they have always been there, but now it seems that they will be closed in the coming days.
Fortnite Item Twitter account: Battle Royale Leaks was very successful in sharing this kind of scoop based on data mining on existing game data and published an image of the gaps. The cracks would be finished on the 21st of this month.
The cracks themselves were the result of the launch of a rocket in the game, a spectacular event that led for a few moments to a generalized peace in the game while people watched, with some exceptions, of course. That was the reason why some objects could move between the world of Fortnite and our world, causing strange situations.
But now, it seems that they are leaving, there is going to be a big change in the appearance of the sky, and it is likely that the change will go to the sixth season. We are in the strange situation of knowing that something will happen, but not why it happens.
