Fortnite Ecosystem v31.00 with Known Issues

Creators can now opt in to a refreshed version of the Creative Content Browser and begin testing in Fortnite ecosystem v31.00. Please provide your feedback on the EDC forums at https://forums.unrealengine.com/t/creative-content-browser-feedback-thread/1956852.

Patchwork gets a new Song Sync device and better memory optimization. LEGO® islands now have the NPC Spawner device, new player tools, and futuristic space Galleries.

We’re aware of an issue where players cannot Favorite an experience while within an island on iOS, and are working to fix this ASAP.

You are still able to Favorite from the Lobby and we’ll provide another update when this has been fixed.

We are investigating an issue with UEFN experiences converted from Fortnite Creative. The Day Sequence Devices, Skydome Devices, and the legacy “Time of Day” island setting may behave incorrectly and be reset to default. We will let you know when we have an update.

We have temporarily disabled backward compatibility checking in the UEFN editor, but it will still be checked and enforced when publishing. This addresses an issue with some creators being unable to build and test their islands.

We are aware of a regression in 31.00 that occurs if you make calls to GetPlayspace from within the block of a class or a class constructor of a creative_device subtype. You may cause a crash when the device runs this code when opening the level, or dragging-and-dropping the creative device into the level. You may also encounter problems when attempting to publish the island, since it will fail the cook process. This will be fixed in a future release of UEFN.

In the meantime, you can remove any such calls within block or class constructor functions as a workaround. You may have to do so before opening your project.
