Not sure how/when it happened, but I've got a bug in bone selection. Two of the bones on my character (both for the foot) are difficult to select. Hovering/clicking directly over the bone does not highlight or select it. The selection area seems to be offset up and to the right of the bone. Also, in pose mode, the manipulators are similarly offset up and to the right, no longer appearing at the tip of the bone.
Any idea how I can fix this?
