These stability fixes comes after Fortnite update 1.21 was released earlier this week. A major patch, this added in a new horde mode, and a lot of other changes. Here’s the 411 on the patch earlier this week:

HORDE BASH ? SAVE THE WORLD
Challenge the Horde

Construct Your Fort

Use your custom fort in all Challenge the Horde adventures.
Your fort carries over to each new mission!

Gather wood, stone, metal and traps for your base from the new Horde mode skill tree.

Bring It Into Battle!

When your squad is prepared, proceed to the combat zone and face off against hordes of husks!
Each zone includes 3-5 challenges, each with increased difficulty.
The final hex hosts especially tough challenges for veteran players.
Each challenge pits you and your squad up against 10 waves of enemies.
Gameplay modifiers are introduced as the waves progress, increasing the difficulty of your foe...
