Broken: 3.0 to 4.0
Worked: never?

Short description of error
I tried to use the Snow character, following the guidelines. But every time I use the Libary Override, the character's eyebrows and neck get stretched and distorted. When the bug does not happen at the time, when saving and reopening the file it appears

Exact steps for others to reproduce the error

Link the CH-snow collection
Object -> Relations -> Make Library Override
Save file then reopen it

There are several depsgraph error message there too... Not so sure about the status of this character (assuming you used the latest version, .002 ?).

Would not consider this as an acceptable bug report anyway, unless studio (rigger) investigate this character and do find a problem related to liboverrides.

I never could reproduce this issue and still can't, in 3.6.5 stable.

Video of me linking, overriding and posing Snow_v2, as downloaded from the website moments before recording.

Edit: Also tried saving and reloading, works fine in 3.6.5 and latest 4.1 as well.

Sigh... I indeed can still confirm the problem... Since nobody else wants to look at it, I had another deeper look into it. Once again, I'm fairly convinced that the problem is in evaluation, due to bad dependency issues for the depsgraph. Console is filled with messages like:

Failed to add relation "Floor"
Could not find op_from: OperationKey(type: BONE, component name: 'ORG-Eyebrow0.L', operation code: BONE_DONE)

Trace:

Depth    Type                     Name
-----    ----                     ----
1        Object                   META-Snow
2        Object                   RIG-Snow
3        Pose Channel             ORG-LTC-Cheek.L
4        Object                   LTC-snow_cheek.L
5        Object                   RIG-Snow
6        Pose Channel             Eyebrow0_1.L
7        Constraint               Floor

find_node_operation: Failed for (BONE_DONE, '')

Investigating the overridden char itself, I found out that several bones are severely offset compared to their expected location, e.g. Eyebrow0_1.L gets pushed towards the left arm, leading to the extreme left eyebrow deform.

Disabling/enabling again its 'Floor' constraint 'fixes' to problem.

Note that some of these warnings are also shown when opening the original Snow_v2 file, so... As I said before, rig needs to be fixed first.

I uploaded a new version (v3) of Snow to the website with the invalid constraints removed.

Meant to upload this when I made my previous comment, but website was broken at the time.

Can confirm that with v3 there are no more warnings in the console, and I cannot reproduce any issue anymore.
