In Outliner’s Orphan Data there are two collections: chair and lotus_plant, they are not used in file but have been set to have fake user. Uncheck fake user if these are not needed in file and click Purge.
And the tree (tree_scatter object) is not linked to scene’s collection. You can make it available with this Python script:
ok, cool …i think i got it… so the collection tree is not seen, because its not in the scene collection that itself is in the view layer…so if i move it into the scene collection it gets viewable and editable…
