Problem with baking LightmapGI and Navigation Region 3d after moving from subviewCOntainer, and subview

Godot Version

4.6.1

Question

I had a SubViewportContainer containing a SubViewport, which held my NavigationRegion3D, LightmapGI node, and other level assets. I decided to change the structure, so I removed the container and the subviewport, leaving only the navigation, lightmap, and the rest of the scene nodes.

Since making these changes, I can no longer bake/render the lightmap or the navigation region. The editor indicates that it is performing the calculations, but once finished, nothing is displayed. It seems the data isn’t being applied or visualized correctly after removing the viewport nodes.

Is this a bug, or wtf?
