Fortnite's Boogie Bomb—which makes your opponents dance on the spot while you watch, laugh, and then shoot them in the head—has been temporarily removed from the game after a player discovered that it allows you to carry an infinite number of weapons and items.

The glitch, as detailed in this thread (with a video), shows the player throwing down the Boogie Bomb at his or her feet and busting a few moves. When the animation is over, they're able to pick up an unlimited number of items, which could be game-breaking: imagine bringing as many shield potions and med kits as you wanted into the later stages of a game.
