Magento - Adding order comments from observer events - magento

Question

I've been really beating myself up over this up, hopefully someone can help me out.
I have a few observer events working perfectly, it's just one that doesn't seem to work.
The creditmemoRefund function won't add a comment to the order. The order 2 work fine, it's definitely firing like intended, and does pull the order object. Why won't it add a comment?
Here's my code...
config.xml
<?xml version="1.0"?>
<config>
<modules>
<Avi_OrderAudit>
<version>0.0.1</version>
</Avi_OrderAudit>

$order = $creditmemo->getOrder();

$comment = "Refund by <strong>".$username."</strong>";

}
}

Answer 1

After
$order->addStatusHistoryComment($comment)
->setIsVisibleOnFront(false)
->setIsCustomerNotified(false);
you need
$order->save();
