Updated revision saved but not displayed

I was able to solve this on my wpengine site by following this: http://wordpress.org/support/topic/update-revision-and-object-cache?replies=1.

To be specific, I edited the revisionary/admin/revision-action_rvy.php file by adding the line:

clean_post_cache( $revision_id );

I added the above code directly underneath the following line:

$db_success = $wpdb->update( $wpdb->posts, $data, $where );

This solved the problem for me.
