a small issue with a rigged mesh.
I have unconnected and unparented bones rigging a mesh (well all bones are parented to a unique “master bone”). Here is the mesh with 3 bones selected
When I apply a Z-rotation I get this, which is not what I want
Strangely, when I append the mesh+armature in a new blender file, I get this, after a Z-rotation :
which is what I want. So why is the behaviour different in the two files ?
Thank you all for your help
