afaict both left and right side are the same in bone relationships. But foot.l is not staying attached to calf.l, even though calf.l is parent and the ‘connect’ button is pressed (see red circle). As you can see I don’t have the same problem with foot.r. There is a dotted line from the bone where it should be connected. I can move it manually into place but what a pain. It is acting exacly as if the connected was not pressed.
