Even though nobody in this support forum helped me, I created a quick way to solve this. Your loop should look like this:
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php if (get_post_type() == 'comic'): ?> <!-- Change this to the ACF field name you need -->
<article><!-- All the code you want without calling ACF -->
</article>
<?php else: ?>
<article><!-- All the code you want with ACF calls-->
</article>
<?php endif; ?>
