Landscape Mountains Project

The solution I tried (successfully) is to

  1. Re-download the (LandscapeMountains_4.8) from Launcher
  2. Build project from it…
  3. Run the project with UE 4.8.3
  4. Migrate the birds blueprint to my project.
  5. Run My project
  6. Drag & Drop the birds blueprint in my level…>>> worked Perfectly
