My client contacted me to say that she tried to edit the page that I set up for her yesterday, and she deleted all the bios. The bios are implemented as an add-more group:

piklist('field', array(
	'type' => 'group',
	'field' => 'board_members',
	'label' => $label,
	'description' => '',
	'add_more' => true,
	'template' => 'field',
	'columns' => 12,
	'fields' => array(
		array(
			'type' => 'text',
			'field' => 'person_name',
			'label' => 'Name',
			'columns' => 12,
		),
		array(
			'type' => 'text',
			'field' => 'person_title',
			'label' => 'Title (if applicable)',
			'columns' => 12,
		),
		array(
			'type' => 'editor',
			'field' => 'person_bio',
			'label' => __( "Person's Bio" ),
			'description' => __( 'Brief biography'),
			'columns' => 12,
			'options' => array (
				'media_buttons' => false,
				'teeny' => true,
			),
		),
		array(
			'type' => 'file',
			'field' => 'person_image',
			'label' => 'Add an image',
			'options' => array(
				'modal_title' => 'Add Image',
				'button' => 'Add',
			),
		),
	),
));

When I asked for more information, she said that she deleted a couple of the bios, edited and added others. Then she pressed Preview. Nothing happened. So she just pressed Update … and all the bios disappeared.

I was able to reproduce this. I deleted the second bio and edited a couple of others. Pressed Preview, nothing happened. Pressed Update and all but the first bio disappeared. This may indicate that if one is deleted, then those after it are also deleted. (One of the bios she deleted was the first one.)
