Worked: 2.79 e045fe53f1b0

Short description of error
A file made in 2.79 containing a external proxy rig has custom properties in 'N' panel.
When the file is opened in 3.2 it rewrites proxies to library override.
The custom properties become locked.

Exact steps for others to reproduce the error

Create empty default file in blender 2.79
File --> User Preferences --> File --> Enable Auto Run Python Scripts
File --> Link --> rig proxy bug file --> group --> rig_proxy
Object --> Relations --> Make Proxy --> rig
Custom property in pose mode 'N' panel affects z axis of Bone via driver.
Save file as something.blend & open in newer blender edition, custom property should be locked now.

Just to make sure:
I am seeing the same thing (Custom Property locked) if I link rig_proxy into 3.2 and making a Libraray Override there directly (leaving out the whole roundtrip of proxy in 2.79)

- can you confirm?
- is this the actual issue you are trying to report?

Yes, confirmed after testing with several rigs.
Yes, I'm a blender 2.79 user still & thought it was an isolated situation but the error is exactly the same.

As an after mention the problem can be circumvented by adding a driver to custom property and using a bone to move it.

What does "Locked" mean here? That you can't create new custom properties? Because as far as I can see, there are no existing custom properties for the armature.

Custom properties need to be defined as overridable in the source (library) file, for them to be effectively editable in a override of linked data. This is a known limitation of versioning update process, besides indeed tricks like adding drivers to work around it, the proper solution is to update the library file in a more recent Blender and set their custom properties as overridable then.

I just leave it here. In case if someone do not know what to do exactly.

Open source file, open settings for each custom property and mark em as overridable with this checkbox.
