MarketPress 2.1.6 killed my marketplace

I upgraded to 2.1.6 and my global marketplace died - though not really, it just returned a "No Products" response. My "browse by category" pages still worked though.

I'm using a custom template file to create and display my marketplace and category pages.

Here is the global products code I am using in the template file, it probably just needs some tweaking to adjust to changes in 2.1.6. In the meantime, I've rolled back to version 2.1.5 until I can work this out. Any ideas how to fix this?

Here is the code I am using

<div id="market-grid">
<?php
$atts = array (
    'text' => 'none',
    'paginate' => 1,
    'page' => 15,
    'per_page' => 16,
    'order_by' => 'rand'
);
mp_list_global_products( $atts );
?>
</div>

I saw int he changelog that the big fix is in for pagination on global products pages, so I'm pretty excited about this new version!
