I've purchased a human basemesh which I intend to use to create various characters and I'm trying to learn how it works first. The mesh has one particular bone that when moved it affects the mesh but when scaled it does not. All the other bones affect the mesh when scaled this is the only one that does not. I've tried to compare the properties of this bone with the others, the properties that can be found in the right side panels (ex: Context Bone, Object Data, Object etc...) while in Armature Pose Mode and Edit Mode and I can't seem to find what makes this bone's scale not affect the mesh. Any idea what could be causing this and where else I should look? I'm using Blender 2.8 which I'm not very used to yet so that could be a factor as well.
P.S.: I should have mentioned it's the jaw bone.
