UE5 World Partition can not delete landscape

I landed here recently, so just for future inquiries, here’s my take on this (Blank, C++ project):

  1. I created a new Landscape, then
  2. I set it, that second Landscape, as project’s default, then
  3. I deleted all children of the old default Landscape, and finaly
  4. I was able to delete the old Landscape member itself
    Hope that helps
