I am rigging a figure with a tail, the first part of the tail connected to the body comes away from the figure when it is rotated, almost as if it is not connected to the body but I have checked the cr2 and it is properly connected and welded.

Is there some way to fix that problem?

There is another problem with the end of the tail, the second last part doesn`t fit properly to the last part and the rotation is not exactly right, can that be fixed?
