Hm, well I couldn’t make that work, but found another solution online that seems to do what I need.
<?php
$libargs=array(
'hide_empty' => 0,
'parent' => 0,
'taxonomy' => 'MYTAXONOMYNAME');
$libcats=get_categories($libargs);
foreach($libcats as $lc){
echo '<div class="col-lg-3">';
$termlink = get_term_link( $lc->slug, 'MYTAXONOMYNAME' );
?>
<p class="text-center"> <a href="<?php echo $termlink; ?>">
<img class="img-responsive img-thumbnail" src="<?php the_field('taximage', 'MYTAXONOMYNAME_'.$lc->term_id); ?>" />
<br />
<?php echo $lc->name; ?></a></p>
<?php the_field('basictext', 'MYTAXONOMYNAME_'.$lc->term_id); ?>
<?php echo '</div>'; }?>
Not real sure why it works over the other method, but it does.
