System Information
Operating system: Windows 10
Graphics card:

Blender Version
Broken: b43077ba3a

Short description of error
For some reason the linked scenes disappear after spending sometime in the master scene. The linked content itself does not disappear, but the listing of it under the "Scene" dropdown. I many times recently, now I think this is a bug.

Exact steps for others to reproduce the error
The untitled.blend file had the linked_29102021_1855_58.blend file linked.

Load the "untitled.blend" file
Open the "Scene" drop down
The linked scene is not listed there. That file is also in the zip file "linked_29102021_1855_58.blend"
Open the Blender File tab (which should be already open in the provided scene)
You can see that the linked scene is not listed there either.

Here is an actual situation in one of my production files.

Opening untitled.blend I dont see linked_29102021_1855_58.blend linked at all anymore.
At this point, the possibly orphaned connection was probably already pruned on save.
Are you sure the scene has not been deleted by accident / for some reason?
So with this example, I am afraid we cannot do much.

But I do experience some (seemingly weird) behavior when deleting a linked scene.
Usually, when you delete some ID that was linked (so it is not used anymore) it is orphaned and on file save/reload/revert that link to the file is completely gone.

#92632.zip

open main.blend (empty file)
link object Suzanne from src.blend (see a link to src.blend appear in the Outliner)
delete object Suzanne again
save/reload/revert (the link to src.blend is gone -- all good)

now do this:

open main.blend (empty file)
link scene monkey from src.blend (see a link to src.blend appear in the Outliner)
delete scene monkey again
save/reload/revert (the link to src.blend is still there - why? dont think anything from src.blend is still used?)

@mont29 : is this expected behavior?

Hi,

This happens with the scenes that are from existing files. I will try to create a better demo file.

@lichtwerk this is usual 'save and load multiple times to get rid of all linked dependencies' issue, nothing special here.

Ah, indeed, if you do it multiple times, it goes away eventually... should have thought of that
