I can not figure out what these orange joints mean. I know usually joints are colored when painting weights, but I'm in regular mode and not painting weights. I'm really wondering because I'm editing a rig I got offline. I'm trying to make the rig game ready, so I'm parenting all the joints to be under one hierarchy, but whenever the bottom-most joint (the regular colored one right at the end) is parented to the theoretical 'next joint', the location of the 'next joint' changes. I want it to stay in its place.

I'm assuming it has something to do with constraints but I'm not really sure what it is.
