Hello,
We’re trying to work with the developers of those games to see if they can restock those games, but there’s a chance they will be out for the rest of the bundle. If they ever do get added then you will be able to claim them from your purchase page at that time.
If you were buying the bundle specifically to get those games then we’re sorry, we can go ahead and refund your purchase and request to disable all other Steam keys you claimed. Please contact support if that’s what you want. Since this is a donation bundle, we don’t offer any kind of partial refund.
Thanks
