Hello, it's the Lies of P Team.
During an investigation conducted by Steam, a technical error occurred which caused an error with the payment system.
The temporary issue regarding the payment system has now been fixed.
Changes have been made to the product settings and now both the Standard Edition and the Deluxe Edition can be purchased.
Further changes are being made to the Deluxe Upgrade by Steam.
All evidence leads that this issue was caused by Steam's configuration changes that were made to our products. We sincerely apologize for the inconvenience caused.
Additionally, purchases that have been made with abnormal payment methods will be monitored with Steam and will be notified through a separate announcement.
Due to the configuration issue caused by Steam, the Deluxe Edition purchase method has been changed as below.
Updated Deluxe Edition purchase method
Original method: Available to purchase the Deluxe Upgrade after buying the Standard Edition
Updated method: Unavailable to purchase the Deluxe Upgrade after buying the Standard Edition.
Users who are interested in obtaining the Deluxe Edition Contents must purchase the Deluxe Edition.
Please note that the Deluxe Edition Upgrade will no longer be available for purchase.
We are deeply sorry for the convince that has happened from Steam's configuration settings.
Warmest Regards,
The Lies of P Team.
