There was a short period where the system wasn't always sending out e-mails as intended. If you've received a PayPal e-mail, that means your order should have been processed properly. If, for peace of mind's sake, you'd like us to have the system send the invoice to you, we can do that. In order to do this, you'll need to PM me with the name and e-mail address associated with the order; I can't help you in any way without both pieces of information.
