Missing information from drawing views

This problem just started occuring a couple of days ago.

I have an existing part/drawing, and then add a new set of holes,save and close.

Later, when the drawing is opened again, the holes are missing butthe dimensions are still there. Rebuild does nothing, so I deletethe view and then undo the delete, and the holes reappear.

This exact same thing happened on 2 different computers.

Has anyone else experienced this? What solutions, if any?
