Cache won't bust on new entry I have a problem with a pair of cache tags refusing to bust the cache when a new entry is added.  The cache works well otherwise.
This is the template code I'm using... it's fairly complex as we're using it to filter products in an ecommerce site.

{% cache %}
  {% set products = craft.entries.section('products').relatedTo(entry).find({limit: 1000}) %}
  {% include 'shop/partials/_product_list' with { products : products } %}
{% endcache %}


This is the include. 

{% for product in products %}
    {% set cat_classes = '' %}

    {% for cat in product.category %}
        {% set cat_classes = cat_classes ~ ' ' ~ cat.slug %}
    {% endfor %}

    {% for cat in product.collection %}
        {% set cat_classes = cat_classes ~ ' ' ~ cat.slug %}
    {% endfor %}

    {% for range in craft.entries.find({limit: 1000, section: 'priceRange'}) %}
        {% if product.price &gt;= range.priceFrom and product.price &lt;= range.priceTo %}
            {% set cat_classes = cat_classes ~ ' ' ~ range.slug %}
        {% endif %}
    {% endfor %}

    {% for days in craft.entries.find({limit: 1000, section: 'leadInTimes'}) %}
        {% if product.leadInTime &gt;= days.leadInFromDays and product.leadInTime &lt;= days.leadInToDays %}
            {% set cat_classes = cat_classes ~ ' ' ~ days.slug %}
        {% endif %}
    {% endfor %}

    {% if product.canBePurchasedOnline %}
        {% set cat_classes = cat_classes ~ ' buy-online' %}
    {% else %}
        {% set cat_classes = cat_classes ~ ' special-order' %}
    {% endif %}

    &lt;div class="prod {{ cat_classes }}"&gt;&lt;a href="{{ product.url }}"&gt;
        &lt;picture&gt;
            ...
        &lt;/picture&gt;
        &lt;div class="pdesc"&gt;
            &lt;h3&gt;{{ product.title }}&lt;/h3&gt;
            &lt;span class="price-from"&gt;£{{ product.price }}&lt;/span&gt;
        &lt;/div&gt;
    &lt;/a&gt;&lt;/div&gt;&lt;!-- /prod --&gt;
{% endfor %}


If anyone has any ideas I'd be grateful!
I fixed it - there was a stuck task preventing the stale template cache from being deleted.
