This is the response I got from Customer Service:
We spoke a while ago over the phone about the Blood Lord’s Lament PDF and it’s missing scenarios. I have been in contact with the webstore team since, and they informed me that the remaining scenarios for that module are not yet released! The PDF will be continually updated with the new scenarios as they come out. If your account is set up to receive emails about updated digital content, you will receive an email when this PDF is updated with the new scenarios as they are developed.
For now, I have been informed those scenarios are meant to be missing until they are released. It seems they are currently in production. Thank you for your patience while I gathered this information. Hopefully you can look forward to the new scenarios being released! Thank you!
