Thank you for your answer John. I have been going through the default WordPress troubleshooting already, without any luck.

I narrowed it down to a filter acf/load_field/key= which is used to fill a select dynamically. The obviously problematic part was a WP_Query object:

function allPosts($field)
{
    $field['choices'] => array();

    $query = new WP_Query(array(
        'post_type' => 'any',
        'posts_per_page' => -1,
    ));

    if ($query->have_posts()) {
        while ($query->have_posts()) {
            $query->the_post();

            $field['choices'][$query->post->ID] = $query->post->post_title;
        }
    }

    return $field;
}

I substituted this with get_posts() and now it is working again (and yes, there is a reason why I didn’t use a relationship field).

But there are still some things I’d like to understand:
a) Why should WP_Query be a problem in this context?
b) Why didn’t this happen consistently?
c) Why should a filter be able, to break the post_name of a field group?

Thank you.
