Not enough information; marking as low priority.

We will keep it on our board for now, in case similar issues arise.

Somewhere in here it seems ?

$list->reloadFromPrimary();
for ( $item = $list->reset(); $list->current(); $item = $list->next() ) {
    $data['items'][$item->getId()] += $item->getApiData( $this->getResult() );
}

Since changed to:

$list->reloadFromPrimary();
foreach ( $list as $item ) {
    $data['items'][$item->getId()] += $item->getApiData( $this->getResult() );
}
