"ID user decrement error"

[mokujinh]

I seem to have come through some errors with the Add-on version after checking the console after blender crashed on me a couple of times.

Here are some screen of the errors and what it causes.

Apparently it causes many fake users and also it crashes blender when I try to open or make a new project as well.

I tried uninstalling the latest UI Version 3 and blender won't crash anymore and the errors won't show up on the console anymore.

This happen to a model I updated from 3.6 to 4.0, (I appended the model to a clean project first).

I tested the older models version in blender 3.6 with the script version of MustardUI and they work fine and the errors won't show on the console either.

Update: Figured out the source of the error may be changing the bone layer name before it being assigned to a specific mesh in the UI configuration mode.

Edit update: the error specifically happens when assigning a bone collection to an outfit part. Changing the name of the bone collection but not assigning it to an outfit part does not produce this error.

Wow this seems like a major issue.

I did see those errors in the console, but I thought it was just a small warning from Blender. Apparently, it isn't.

Let me check. :)

It seems like it's a Blender bug. I reported it: https://projects.blender.org/blender/blender/issues/116061

It seems it will be fixed in Blender 4.1 :)
