I am working on a project with many characters - each linked from one single .blend file, using library overrides.
The outliner in the image below shows the source file for the characters. I really like the library override system - everything is working perfectly and exactly as intended - until I open the exact same file on a different system, save and re-open.
All the characters 'merge' into one armature. The image below shows that the library override icons are still present.
I have checked that paths are set to relative on both systems, and each system is using the exact same Blender version 3.0.0
Why this is happening is just beyond me, hence this request for help. Has anyone experienced this and figured out a solution before?
