I just noticed recently when I am looking through messages with contacts that have a long history. (never deleting any messages) that while scrolling up it will display messages from months back, out of order, or show random pictures. For example if I am scrolling up and have had a conversation with someone this week, it will show messages from 3 months ago and skips anything inbetween until I get to the point where it tries to refresh the messages; it will then add some in between the more recent conversations and the past ones; but still is far out of order. Is this a feature or bug from iOS 8.3?
