Short description of error
[Please fill out a short description of the error here]

Exact steps for others to reproduce the error

Save the library.blend and problem.blend in the same folder
open the problem file, notice that object "JBUJeans_9015.Shape.001" is not a child of "rig-dz0.004"
in outliner with "JBUJeans_9015.Shape.001" selected, use context menu "Library Override >> Make >> Content". You may have to do this twice to see the blue jeans snap to fit the the character mesh (via a surface deform).

In more complex files, even if I save this result (parenting fixed), the problem often returns. This also prevents me rendering from a script (the displayed script fails). related issue

open the problem file, notice that object "JBUJeans_9015.Shape.001" is not a child of "rig-dz0.004"

Maybe the file was saved in a later step? "JBUJeans_9015.Shape.001" appears to be a child of "rig-dz0.004":

Could you check this?

I edited the description to include the new files.
But again, I can't follow the steps, as I can't find the "JBUJeans_9015.Shape.001" object.

Thanks for the report, but would it be possible to simplify the .blend file and provide replicable steps?

In the meantime, in Blender 4.2 (Alpha), when opening the problem.blend file, I experienced a crash.
Maybe the file is corrupt?
@mont29, does this crash ring any bells?

@mano-wii I believe the crash was also reported in #118299, should be fixed by 88ba4dfaa3.

@mano-wii I believe the crash was also reported in #118299, should be fixed by 88ba4dfaa3.

I have tested with latest nightly build (blender-4.2.0-alpha+main.fbf47b9a126a-windows.amd64-release) and it crashes: EXCEPTION_ACCESS_VIOLATION.

To recreate:
open problem.blend
for object "JBUJeans_9015.Shape.001", contxt mnu library troubleshoot resync (once or twice).

This is a different (albeit related) issue, caused by shapekeys special case. Next time, it's better to open a new report, rather than re-open a closed one.
