Importing a 8192x8192 .r16 landscape file does not render landscape in level viewport

Importing a large landscape, such as 8192x8192 or 8129x8129 into a project shows that a landscape has been created, however the landscape itself does not render in either wireframe or perspective views. The actor seems to exist but the file never properly imports.
