in the Attribute editor, check on Joint (under Transform Attributes) > Draw Style. Should say "Bone". That's my best guess. Also, check your camera's clipping plane in the Attribute Editor... there are numerous sources of info on the clipping plane if ya don't know what that is. Yep, its says "bone" I even downloaded a bug fix from autoudesk to see if that corrects the issue but I still get the same thing, no connecting bone. I did a search and found a few others with the same issue and no one seems to be able to fix it. This is just perfect..lol.
