Not sure if this is OPC related but it is related to guest checkout so I'll go ahead

1. The order confirmation email sent to the customer has a link to the order_status page - great.

2. If I update the order then the order update email contains a detailed invoice link to the account_history_info page - which is no good as the customer doesn't have an account.

So it seems that an order update sent to a Guest needs to include #1 not #2, not sure if there's something clever in Admin that will allow this.
@simon1066, thanks for the report. I've created a GitHub issue to track the change required.
