System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.79

Blender Version
Broken: version: 3.3.0 Beta, branch: master, commit date: 2022-08-22 16:15, hash: 4fecf652e2
Broken: version: 3.4.0 Alpha, branch: master, commit date: 2022-08-22 16:16, hash: 7f6cd405b9
Worked: unknown

Short description of error: If a linked object's material references an empty, it will cause other data-blocks to be removed without warning when reopening the Blend File.

Long description of error:
Under very specific conditions, linking certain kinds of data causes the "Override Auto Resync" to remove a collection. In our case a collection named LibA that contains ; object & material, the material uses a texture coordinate node which references the location of an empty. This LibA collection is the linked into a SCENE file. A second arbitrary asset LibB is also linked into the collection.

Now the file contains 2 LINKED collections:

LibA(object's material references an empty)
LibB (any other asset)

If the LibB file is renamed the function "Override Auto Resync" is called when this SCENE file is reopened. During this function if the LibB blend file was renamed it will be removed without warning.

Exact steps for others to reproduce the error

Create LibA.blend File with LibA collection with a material
Add a texture coordinate node that references an empty to object in Collection LibA
Create LibB.blend File with LibB collection with any data
Create a Scene file that references LibA.blend's LibA Collection and LibB.blend's LibB Collection
Create Library Override on LibA + LibB
Rename LibB.blend file
Enable "Override Auto Resync"
Reload Scene.blend
LibB Collection will be removed from outliner

Exact steps for others to reproduce the error
Based on files: override - tester.blends.zip

Open SCENE.blend notice the reported error after LibB is renamed
Enable "Override Auto Resync" if not already enabled
Reload Scene.blend
LibB Collection will be removed from outliner
