Hey again coleburg,
Unfortunately no, the bug is not fixed in this version. The importer is originally created to make a transition from old Membership plugin to Membership 2 on the same site.
The issue we experience with using it to export info from one site and import it to another is that PayPal for example has the post_id of the invoice, and when importing the invoices on another site the post_id on the new site is different, so Membership 2 can’t link the PayPal response with an existing post/invoice after import if that makes sense.
Our developer is currently working on a solution that will hopefully allow us to export info from one site and import it to another in the future.
Best regards,
Bojan
