Short description of error
Hello,
After move or rename it a link file, you break dependencies in others files.
So, you need to use operator "find missing files".
But, if this link is overridden, after using"find missing files", you loose overridden data.
#79591.zip
T79591_main.blend
Cube
linked fromT79591_src.blend
and overridden (transform moved up in Z by 3)T79591_src.blend
into the "moved" folderT79591_main.blend
again (links are broken - this is expected)Original report
1- Link a blend file (like collection), overrided data and save a new file.
2 - Move or rename the link file
3 - Open the saved file which contain the overrided data.
4 - Use operator "find missing files" to restore link and save.
5 - Now, open again or revert, link is restored but overrided data are lost.
Thanks!

Note that
find missing files
is more intended for image or video files for example, it indeed does not do any 'smart' things when dealing with Blender library files, besides updating their file path... Actually reloading the library would be nice, but that is more like a TODO, definitively not a bug.Proper modern way to deal with moved libraries is to use the relocate operation on them in the Outliner, blendfile view.
That being said, overrides should not be generated or updated when reference linked data is missing, will fix that.
