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.
