Unreal Keeps deleting objects from my Scene, how do I prevent this?

[3dRaven]

Were these assets imported from a local drive? Are the assets source models (e.g. fbx files) on your local drive?

Are these objects in the main level or a sub level?

If you are using the world partitioning system the this might help

All of my actors except a few suddenly say [Unloaded] and are hidden, what is this?

nevermind I made it work. in the world partition window you drag a selection over the part of the world you want to have loaded then right click and select “Load Selected Cells”
