During Season 4 a Rocket Launch took place causing a Rift to be opened in the sky above the Fortnite Battle Royale map. Now over a month later in Season 5 dataminers are seeing signs which point to the Rift shrinking until it disappears in the files and API of Fortnite. Below is an image showcasing a shrunken Rift which is said to be what the Rift will appear as on August 18th, 2018 – 3 days before it entirely disappears.
