해외 포럼을 보니 이번 험블 먼슬리 3개월 프로모션 관련해서 험블에 직접 문의하고 답변을 받은 사람이 있었던 모양입니다. 

아래 내용은 답변 전문이라고 합니다. 

"This is a mass response to all users who have received an email in regards to Kingdom Come Deliverance being provided as a free game when purchasing a 3 month subscription. If this ticket doesn't address your questions or concerns please don't hesitate to let me know as I will be happy to help out!

Hi there,

Thanks so much for getting in touch with us. I want to express my sincerest apologies for the issues or confusion this promotional email may have caused. I am happy to offer some clarification as well as some additional information that I hope is helpful.

We have sent out an email erroneously to users that may not have qualified for the promotion to receive Kingdom Come Deliverance for free if you purchase a 3 month subscription. Hopefully you have now received our follow up email clarifying this error if you were already an active Humble Monthly subscriber! One of the qualifying factors for this promotion was that you needed to not already be an active subscriber as detailed at the very bottom of the original email. This is a type of promotion we try out from time to time for select users, and we are always working to find great promotions for everyone whenever we can. If you in fact did not receive this promotion at all I am terribly sorry as we can only extend this offer to users who did receive the email for their personal account! I apologize that in this case we clearly missed the mark as we are making adjustments to make sure this doesn't happen in the future.

For any user that received this promotion email: You are welcome to purchase the 3 month subscription gift using the link from the email (it will be a gift intentionally). Even if you have an active subscription we will still uphold the promotion for you to receive Kingdom Come Deliverance! Please keep in mind you must have received this email personally (not forwarded from another email or friend) to be eligible to receive Kingdom Come Deliverance. After you purchase the 3 month subscription gift to Humble Monthly and apply it to your account you will be eligible to receive the game when it is sent out later in the afternoon of October 24, 2018.

If you have already made the purchase before this response or our apology email worry not! You will still be eligible for the promotion as long as you made the purchase from the account who received the initial promo email.

Once again, I want to wholeheartedly apologize for how confusing and potentially frustrating this ordeal has been. Thanks so much for working with us with your unwavering patience! As always if you have any questions or concerns don't hesitate to reach out to me!

Sincerely,

-Mathew Humble Bundle"

요약하자면 3개월 먼슬리 구독시 Kingdom Come Deliverance를 지급한다는 내용의 이메일을 받으신분들은 기존 구독자라 하더라도 Kingdom Come Deliverance를 받을 수 있다고 합니다. 

즉, 이메일에 첨부된 링크를 클릭해서 나온 결제 페이지에서 '기프트' 로 결제하신 뒤 본인 계정에 적용하시면 3개월 연장은 물론 Kingdom Come Deliverance 까지 같이 받을 수 있다는 내용 같습니다. 

다만 실수로 인해 잘못보내졌다는 메일을 추가적으로 받으신 분들에게까지도 위 내용이 적용되는지 여부에 대해서는 분명하게 나와있지 않아 아쉽네요.
