I am working with a fairly simple rig, as I'm pretty new to rigging/animation in general.
I created my bones, and later parented my mesh to the armature with automatic weights.
Later, I wasn't happy with some of the bone positions/sizes/orientations, so I moved them around in Edit mode.
I visited this question, in what I thought would be a simple way to recalculate the automatic weights. However, nothing appears to happen? Am I doing something incorrectly, or is there some type of problem keeping these weights from being regenerated.
In the provided gif, note that the weights stay the same after the bone is dragged way out of position.
