Strange resolution edit: So, turns out the link email for the september update, had the subject line [itch.io] Under Her Command - Femdom Visual Novel - Under Her Command - July update is here!" Making it blend in with all the other itch news subscription updates.
Double check to see if you have a "July" update email, dated in this september, people.

Hello SectionZ, we are sending the links to our buyers as emails as we can't put the download links without putting them behind a paywall and if we put a price, the game gets deindexed. If you have paid for the game, please check your mailbox. If you have unsubscribed from the mails, please reach out to mortedara@hotmail.com so we can send you the link of the game.
Well, turns out the error is even stranger. The Itch.io sent email with the september update mega link inside I got? It has the subject tile "july update is here!" with no mention of September. Which is why I swept it up with other 'Just news updates' emails. "Wait a minute... Why is this under her command july update email dated yesterday *opens email to see it talking about september*... ARE YOU SERIOUS!?"
Will edit my first comment shortly to make it clear "Double check your under her command emails, it might look like a useless july email". Just leaves the question "Pure Itch automation mistake, or Dev accidentally forgetting to change the subject line for the new build?"
