Fortnite’s new creativity-focused Playground Mode has returned to the game, days after developer Epic Games was forced to take it offline due to technical difficulties.

The Playground Limited Time Mode debuted as in Wednesday’s patch v4.5, but just a few hours after its release, Epic took it down. Playground is far and away the most anticipated Limited Time Mode in Fortnite’s history, which made its all-too-brief appearance after patch v4.5 even more disappointing for fans. Thankfully, it’s now back on the live servers, and Epic has even provided the community with a few details about what exactly went wrong.
