Various dataminers have shared that Fortnite could be getting an unexpected UI change in one of the next game updates. Despite being out of early access for a while now, Fortnite is an ever-changing game, and it receives regular updates and patches every two weeks or so. Since it's an online multiplayer game, the developers keep an eye out so they can act fast if any error occurs or if any balance changes need to be made. This kind of attention is particularly important when tournaments with cash prizes on the line are live.
