Replace string variable inside loop

I have a loop in twig/symphony, like so:

{% for breadcrumb in page.breadcrumbs %}    
  <a href="{{ breadcrumb.url | url }}">{{ breadcrumb.title }}</a>
{% endfor %}

I'm trying to check the first variable in the for loop. If that equals Artists then the html part need to be replaced by a new piece of code.

So what I did was this:

 {% for breadcrumb in page.breadcrumbs %}

  {% if loop.first %}
  {% if breadcrumb.title == 'Artists' %}
  <a href="{{ 'artists' | url }}">{{ 'Artists' | t }}</a>{% else %}<a href="{{ breadcrumb.url | url }}">{{ breadcrumb.title }}</a>
  {% endif %}
  {% endif %}

  {% endfor %}

This works however when the bradcrumb path goes deeper then two levels then everything after the second level isn't shown anymore. So what I mean is this:

home > Artist > //nothing shown here anymore. Loop stops I think??

Instead of 

home > artists > category1 > subcategory 2

Does anyone know what I am doing wrong. Why does the loop stop with this code?

The loop keeps going, but you've wrapped the entire output logic into the loop.first variable conditional.

You need to do this instead:

{% for breadcrumb in page.breadcrumbs %}
    {% if loop.first and breadcrumb.title == 'Artists' %}
        <a href="{{ 'artists' | url }}">{{ 'Artists' | t }}</a>
    {% else %}
        <a href="{{ breadcrumb.url | url }}">{{ breadcrumb.title }}</a>
    {% endif %}
{% endfor %}

This way you are checking for both the first iteration of the loop and whether or not the title is "Artists"

You're only checking the first iteration (first loop), and do nothing with the rest:

{% for breadcrumb in page.breadcrumbs %}

    {% if loop.first %}
        {% if breadcrumb.title == 'Artists' %}
            <a href="{{ 'artists' | url }}">{{ 'Artists' | t }}</a>
        {% else %}
            <a href="{{ breadcrumb.url | url }}">{{ breadcrumb.title }}</a>
        {% endif %}
   {% endif %}

{% endfor %}
