Hi ForbiddenChunk! You should use the post ID instead of the post object in the post_parent argument. Take a look at this, may helps you in the future https://gist.github.com/luetkemj/2023628

<?php
$post_object = get_field('second_subpage');

if( $post_object ): 

// get the post id from the post object
$post_ID = $post_object->ID;

// override $post
$post = $post_object;
setup_postdata( $post ); 
?>
    <!-- here -->
	<?php
	$args = array(
	    'post_parent'    => $post_ID,
	    'post_type'      => 'page',
	    'posts_per_page' => -1,

	    'order'          => 'ASC',
	    'orderby'        => 'menu_order'
 	);

	$parent = new WP_Query( $args );

	if ( $parent->have_posts() ) : 
	while ( $parent->have_posts() ) : $parent->the_post();
	?>

	<div class="page_link page_link--small count_five" style="background-image:url('<?php the_post_thumbnail_url(); ?>');">
		<div class="page_link__title">
			<h2><?php the_title(); ?></h2>
			<?php the_field('preview'); ?>
		</div>
	</div>

<?php endwhile; ?>
<?php endif; wp_reset_postdata(); ?>

    <!-- end -->
<?php wp_reset_postdata(); ?>
<?php endif; ?>
