Hi, thanks for the report. Can confirm if pivot point is active element and snap target is set to center

Hi @AdamEarle,

According to the video, in 4.1 you are using the Median Point as the Center, while in 4.0 it is the Active Element.

There is no bug here, the Snap With Center option uses the Transform Pivot Point as the Snap Base Point.

In other words, you are moving this point that I marked yellow to the snapping point.

However, the question remains: why is the active point not the selected point.
In fact, there may be a bug.

The code that sets the Transform Pivot Point Active Element as being the "Head" of the Bone is explicit and has always worked like this:
https://projects.blender.org/blender/blender/src/branch/main/source/blender/editors/object/object_utils.cc#L65
https://projects.blender.org/blender/blender/src/branch/main/source/blender/editors/object/object_utils.cc#L110

This happens because a bone does not have an "Active element".
From the code we cannot know which "Element" was selected last (Head or Tail).
We can only know which bone is active:
https://projects.blender.org/blender/blender/src/branch/main/source/blender/editors/armature/armature_select.cc#L1121

I imagine this could be improved, but I don't think it is considered a bug given how long it's been working like this.
