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. --- _[View the full topic](https://forums.unrealengine.com/t/fortnite-ecosystem-v31-00-with-known-issues/1978173)._
