Description

The Nav Mesh is appearing in the editor, but not appearing during PIE when its Z value is set to a size similar to the floor size that it is generating on.

Making the Nav Mesh Bounds Volume taller resolves the issue.

The licensee has also provided a test project showcasing the issue which they've linked in their thread.

Steps to Reproduce
  1. Open the editor
  2. Create a new "Empty" map (File->New Level->Default)
  3. Add a Nav Mesh Bounds Volume at 0,0,0
  4. Set it's size to 1000,1000,50
  5. Enter the Show Navigation Console Command (notice the Nav Mesh shows up)
  6. PIE and enter the Show Navigation console command again

Result: Nav mesh appears in-editor but does not appear during PIE

Expected: Nav mesh would appear in PIE as well as in editor.
