Fortnite Update 13.20 added fixes for over a dozen bugs, including one that caused the Sandstorm outfit to appear without hair when equipping the "No Mask No Cowl" style.
Other general Fortnite fixes included adding the missing styles for the Specialist Pickaxe and Arroyo Pack Back Bling, removing Rage emote fire effects after use, and preventing emote sound playing over Main Stage music in Party Royale.
In the battle royale mode of Fortnite, Epic Games removed fall damage when dropping from a zip line into shallow water, fixed Epic and Legendary submachine guns being unable to Sidegrade, removed the ability to contribute to Storm Surge by damaging Marauders, prevented future supply drops from pushing loot under the map, and ensured Chug Splash correctly heals players when thrown inside of a bush.
In Save the World, Epic Games fixed a bug that made the Storm King's area of effect attack leave the map covered in a bright pink texture. The developer also removed a soft-lock in user interface functionality when opening Llama in Llama Shop, and fixed Lobber projectiles damaging players or objectives near a wall.
Finally, Mobile received a fix to prevent players from changing between Build and Combat mode while holding down the fire button.
Fortnite Update 13.20 also added the Flare Gun to the game.
