System Information
Operating system: Windows 10
Graphics card: RTX 3090

Blender Version
Broken: Blender 3.2 official release. Tested on 3.21 release candidate of june 27th

Please note that the provided rig may not be distributed. I attached it here to help you reproduce the bug.
Please kindly remove the blend file once working on the bug.

Short description of error
If I link my character and, (got a master collection and 2 child collection, one for the armature, the other for the mesh objects) make its collection an Override hierrarchy.
If I save the file in 3.2 and re-open it, leg rigs will bug. The corresponding bones will lose their target in the constraints.
If I manually fix it, and reload the file, the previous bone in the hierarchy will loose it's constraint target too.

A fix is too Resync override in the outliner each time I re-ope the file.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Link the Trident-character collection.
Make it an Override Hierrarchy.
Save the file.

Re-open the file.TRIDENT-RIG_final.blend

Thanks for your help

Thanks for the report. Unfortunately the scenario described is too time consuming for us to track down, we require the bug reporter to narrow down the problem.

Normally .blend files can be simplified by removing most objects and disabling settings, until the problem reveals itself more clearly.

There is an invalid driver in the file. Could it be that it's related?

Hi,

Thanks for your feedback.
The driver error is not related, It's just an unassigned.
I will further investigate.

Investigating the issue, this is caused by the undefined behavior of misconfigured constraints (in the case without a bone specified):

It's not a bug, but a user error.
