The plugin can’t save actors that don’t exist in the world any more.
i think you want to use node “Save Level” before you unload them, this node will save all actors of a streamed level you pass in, you can even save it to it’s dedicated slot.
And can also force a streamed level to reload with “Load Level” node whenever needed as well:

Remember to create “New Slot Instance” before using nodes like these.
