It's nearly been a week since Fortnite: Battle Royale's latest update arrived, but its most-anticipated new feature, Playground mode, has still yet to emerge after a rocky debut. Fornite creator Epic Games has been since working on a fix, but so far, there's no date set for Playground's return. 

But once the update dropped, Fortnite's multiplayer matchmaking began to break, forcing the company to roll the update back while it worked out the bugs, GameSpot reports. The game itself is still working smoothly while the errors are being fixed, but you'll have to wait for these new features.
