I am on 10.0.2 and I just discovered that I have "disappearing" messages too. I generate a message and send it to nurse to call Pt with something. If she calls, leaves a message, forwards to herself waiting for the patient to call, then patient calls, she writes something there and then saves to Pt chart it goes without any problems -saved. But if pt answers the phone right away and she saves this message without forwarding to herself first, then it disappears. There is a message in pt chart with no text.
