### Summary I am new to UEFN and am unable to make testing levels in the team project because everything I place into a level shows up as (unloaded) and causes errors and slows things down to the point where the editor is telling me to enable streaming. It started after I tried to create Playsets as shown here [How to create new Prefabs using Fortnite Props? - #4 by JustDrewTV](https://forums.unrealengine.com/t/how-to-create-new-prefabs-using-fortnite-props/1254170/4) and I set the World Setting to ‘is prefab’ Now the main level pulls everything into itself from levels I create. My teammates have not seen this before. Do you know why this is happening? I am also experiencing many crashes but I do not know if that is related. ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing? Island Settings ### Steps to Reproduce 1. Make a level that is not the main island that loads on play 2. Put props in level 3. Go to world settings 4. Next to “IsPlayset” make sure that is checked. 5. save ### Expected Result I expected the level to become a ‘playset’ with similar functionality to a prefab. ### Observed Result My island settings for the prefab level were pulled into the main level unloaded and my team and I could no longer load a session. In addition, everything else in the prefab was pulled into the level. After I unchecked and deleted the offending level/attempted playset, the behavior remained the same. All levels I create are being automatically brought into the outliner of the main island as unloaded, yet are also affecting performance and contributing to crashes. ### Platform(s) Windows 11 Intel(R) Core™ i9-10980HK CPU @ 2.40GHz 3.10 GHz Installed RAM 32.0 GB (31.8 GB usable) System type 64-bit operating system, x64-based processor ---

When I switch between the level with assets and the main level it usually crashes, this time with this error. Fatal error: [File:Z:\UEVFS\Root\Engine\Source\Editor\UnrealEd\Private\EditorServer.cpp] [Line: 1934] World Memory Leaks: 2 leaks objects and packages. See The output above. I have noticed things slowing down and have had multiple memory leak crashes. ---

I still haven’t fixed the issue but I do believe the crashes were unrelated to my playset problem. They cleared up after the major system maintenance that had uefn down for six hours. ---

Hello, In your GameFeatureData asset, are all ‘Base Maps’ arrays empty? ---

I just noticed[this thread](https://forums.unrealengine.com/t/data-layers-always-visible-on-older-projects/2108759/29) that got recently bumped. It sounds similar to what you’re seeing. A post there suggests clearing your intermediate files.(\AppData\Local\UnrealEditorFortnite\Intermediate\ValkyrieUploadTemp) Let us know if that solves it for you! ---
