System Information
Operating system: Windows-10 64 Bits
Graphics card: GeForce GTX 1070 NVIDIA 441.66

Blender Version
Broken: version: 2.83 (sub 1), branch: master, commit date: 2020-01-18 19:00, hash: c2e62c1292
Worked: (optional)

Short description of error
If I relocate a linked blend file and save (Ctrl+S) the current file, Blender crashes. I believe this only occurs if the linked collection is disabled in viewport (and it has a library overriden armature).

Exact steps for others to reproduce the error
1- Launch the provided Suzanne.blend file inside Monkey folder.
2- Right click to the broken linked file in the outliner and select relocate.
3- Go to parent folder (Alt+Up Arrow), double click Cube.blend
4- Save (Ctrl+S) and Blender will crash.

Can also confirm it is not crashing if the linked collection is not disabled in viewport

Our beloved Bone pointers in pose data… Pretty sure I know what happens and how to fix it even before investigating that bug! xD
