When a design changes and dimensions loose their connections we get dangling dimensions on the drawing. Happens all the time. I have no problem (ok, few problems) going back and reattaching the dimensions if only one end point is broken, but, I have never been able to reattach a dimension if both of the end points are broken. I have always had to recreate the dimension. Is that the case for everyone? Or is there something I don't know about?
