Worked without issues. Did it from my phone. Thanks for posting it on the forum.

This happened to mine as well, it was in my account for about an hour and then disappeared.

According to the images on Humble's instruction page for GOG purchases, we were supposed to see an Activated page, similar to what we see when we buy a game at GOG, with the Go To My Account button.

So clearly something is not right when so many of us get a 404 page, and some don't see it in their library or only see it there temporarily.

Is linking with Humble permanent? I know it is with Steam and GOG Connect.

Also got a 404 but the game is in both of my GOG and Humble library now. No email from GOG but from Humble Bundle.

edit: received an email from GOG titled Items added via Direct to Account feature today.

Humble has been selling GOG keys for a while now.

i really didnt know! i observed this community wish from wishlist https://www.gog.com/wishlist/site/humble_bundle_support_and_keys and there is not even "in progress", let alone "finished"

Same here.

The game first appeared in my library, then disappeared, and then reappeared (both in the library and in the orders history) after about 4 hours since the moment it was redeemed. I also received a confirmation email from GOG that this game has been added to my account.

It looks like there are some delays due to a large number of users who decided to redeem the game.

Get the 404 on my redemption attempt but then find the game to be safely nestled in my library.

There's no need to assume anything - the linking of accounts is usually done based on a unique identifier. I find it extremely unlikely Humble Bundle will store any credentials except its own. It's more likely GOG has given them an API key based on which they can perform certain operations on GOG users (assuming they provide said unique identifier), such as add games to them.

For example, here's SmollestLight's user ID (and online presence as listed by the Galaxy API): https://presence.gog.com/statuses?user_id=52857781047288620

Now if I were Humble and had a pre-esablished API integration with GOG and an agreement to add game X to that account, I'd be able to do that. No credentials required. Thanks for letting us know.

Curious that this game would be used to promote GOG, when it's reportedly two versions behind on here: https://www.gog.com/forum/seven_the_days_long_gone/patch_133

I thought of that when I saw the game was a GOG version.

So we're missing out on 2 patches:

1.3.2 -> Japanese Localization
1.3.3 -> Includes a fix to a quest called "Very Old Friends"

From what the devs say in the changelog, without patch 1.3.3, this quest cannot be completed.

All right, also received the e-mail about the order and have it show up in my orders list on GOG, half an hour ago, so a delay of almost 16 hours. But saw the game in library and could download it right away.

And yeah, also noticed that, the missing patches. And Marko saying he received no reply when he tried contacting the devs.

The game is now back in my library and in my Order History.

I woke up a while ago and saw some emails from GOG.
One was a receipt for the game.
The other from Support had some refresh links I needed to click, which did the job.
All good now.

Thanks DEVs, Humble & GOG.
