"Overfall" keys revoked by developer [Updated - 4]

I've just got a Steam pop-up (and apparently wasn't the only one) saying that the activated product code has been removed from my account. As further explanation it says "Your recent Product code activation has been revoked due to a problem processing payment for this item."
Here's a screenshot: https://i.imgur.com/dXgiCYW.png

The game was part of Fanatical's 'Origins Bundle' and could also be purchased as part of Fantical's 'Staff Picks 2018 (Build your own bundle)'.

I had won the game here on Steamgifts and activated it the same day on 8th September 2019, 6pm. The developer made a post on the games community page on Steam:
https://steamcommunity.com/app/402310/discussions/0/3068614788761423239/
In that post they've linked a google form for you to fill out in order to claim a replacement key - if you still have the original key and know where you've bought it. [Warning: It is advised not to use that form as supplying the requested information has the potential to render your Steam account vulnerable to be claimed by third parties.]
In short it says "they were going to pay us after-sales. Unfortunately, we got scammed by them and couldn't receive payment."

Update 1:
Fanatical published a little statement on the issue: https://support.fanatical.com/hc/en-us/articles/360018863437

Update 2:
Another dev made a second statement (https://steamcommunity.com/app/402310/discussions/0/3068614788762142906/) about the issue and apparently they want to let fanatical replace those keys originally sold by them.
What the statement fails to address is what is going to happen with the data that people already have provided in their original Google form.

Update 3:
Fanatical have updated their blog post with part of it saying: "we have received new keys that we are in the process of sending you over the next couple of days."

Update 4:
According to an update from 6th April, 11:51 am to the Fanatical blog post about the issue, they are now in the process of replacing the keys and sate that the system will notify you via email once the new key is in place. They also clarify once again that this issue was caused by the wrongfully doing of the game's devs.
As for revoked keys from other shops - there's no info on that as far as I'm aware.
