System Information
Operating system: Windows-8.1-6.3.9600-SP0 64 Bits
Graphics card: GeForce GTX 860M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 445.75

Blender Version
Broken: version: 2.83 (sub 13), branch: master, commit date: 2020-04-11 15:16, hash: 85de07e64c
Worked: (newest version of Blender that worked as expected)

Short description of error
If you close a file with a node group being edited, the usercount gets messy.

Exact steps for others to reproduce the error

On the default blender file go to Shading workspace
Select Principled BSDF and create group (Ctrl G)
Save file
Close file
Open file

or

Open attached file

Finally, exit the group.
You see the nodegroup user count is 2 instead of 1

thank!

A fix was recently committed in this area.
Maybe this is a remnant of an old file with the problem?
Anyway there should be a way to remap the users.

@mont29, I don't know how to debug usercount. Is there really a bug here?

After rereading the "short" description I realized that the problem is reproducible in any file. So it's a bug.

sigh... So basically node editor is completely schizophrenic, some part of it consider itself a real ID user, others just a 'user one' one...

Luckily this does not seem to hard to fix, although it may be difficult to ensure all cases are now properly handled, but this we can easily iterate-fix if needed.
