mail attachment + invoice

[p.barg]

Hi there,
using VM3.0.2 and Joomla!3.3.6.
I would like to send a general mail attachment for order status 'comfirmed by shopper' and 'confirmed' and an invoice for
order status 'confirmed'. Whereas each attachment works fine on its own, only the general mail attachment is sent if both
are enabled for order status 'confirmed'. Is this a bug or can a specified order status only have one mail attachment
(either invoice or general mail attachment)?

Regards

Petra
