Add bones to an armature deformed in pose position I have a simple pistol model with one root bone.

It has a Childof constraint to the hand-bone of a character.
Now I want to add a new bones to the Pistol armature, so I go to edit mode, which shows the rest position then, add a bone there and define the root as parent of the new bone.

When I go back to pose psotion then and pose mode, the new bone is rotated like this:

Any idea how to fix it or what's the problem?
Thx!
Your new bone is green in Pose mode, it means it has a constraint, just delete this constraint.
