Migrate ElectricDreams Sample Level to my project

I want to migrate the UE5 Sample Map/Level of ElectricDreams_PCGCloseRange into my current project but am having difficulties. I do not want to simply migrate my Game Mode into ElectricDreams in order to lower the file size when I publish the game to share with my friends.

I get a host of errors (53) within Message Log (Map Check) when completing the migration on my project.

Non-spatially loaded actor /Game/Levels/PCG/ElectricDreams_PCGCloseRange.PCGDemo_GroundBP references Spatially loaded actor /Game/Levels/PCG/ElectricDreams_PCGCloseRange.Rock_B_BP

I even copied the DefaultEngine, DefaultEditor & DefaultGame files from ElectricDreams Config folder into my projects Config. But nothing seems to work.

Hoping to understand what I’m doing wrong.

In the same position; I was able to migrate some individual assets over after enabling Substrate per this guide, but I can’t seem to migrate entire levels without everything breaking (even if I copy the Config folder contents.)

If anyone encounters a solution, let me know.
