My contacts sometimes leave for a spell and come back. I suspect is has something to do with syncing my contacts to various cloud services.

My main problem is with duplicates. Seems when one disappears, it will reappear later but have the exact same entry listed twice. I know the contact itself deletes or becomes unavailable because any messages I have from that person will just show an unlinked email address or just their number (in the case of an SMS)
