Version 7.0.0
This is an issue introduced somewhere in one of the previous updates of version 6 and it’s still there in the version 7.0.0.
When cloning an order, the link to the issued invoices is kept in the new order. This is not useful, since the cloning of orders is mainly thought for duplication of orders, not for their invoices.
In the version 6.0.5 it is occurring too.
