Bought HIB Eets Munchies Early-Access "BEFORE" HIB 9 out get Don't Starve for free

Klei Entertainment didn't give an information about this in Humble(Link) but I ask them through Facebook

Here is my conversation asking about Don't Starve in Humble Bundle Eets Munchies Early-Access Beta and this is the picture to prove my word

Me :

Dear Klei Entertainment

I bought your Humble Bundle "Eets Munchies Early-Access Beta" $6.99 from here http://www.humblebundle.com/store/eetsmunchies?preview=pending before you added it in Humble Bundle 9 and I checked it before HIB 9 out and it still don't have Don't Starve Steam and Chrome key, but I just checked it a min ago(After HIB 9 out) and saw it has Don't Starve Steam and Chrome key in Humble too, so you add it for people who pre-purchase Eets Munchies? If so I am very thank you, appreciate it. Or it's some kind of Errors. Let me know what it is
Thank you

Klei Entertainment :

It's a gift! Because you bought our beta of Eets and helped us test it, you get Don't Starve for free! Enjoy.

So check on your HIB account. I just checked it and got 1 copy of Don't Starve steam key and Chrome key = you buy Don't Starve only $6.99

"Note :" Even you buy HIB Eets Munchies Early-Access Beta right now, you WILL NOT GET Don't Starve 1 copy. I asked Klei Entertainment about this too

Me :

Ty very much, very appreciated it and ty for the quick reply, will looking forward to your new game in the future

and may I ask you last question? if other people buy it("Eets Munchies Early-Access Beta" $6.99) after Humble Bundle 9 is out, they still get Don't Starve or not?

Klei Entertainment :

The Don't Starve gift was for people who purchased Eets: Munchies "BEFORE" the Humble Bundle. Buying Eets inside the Humble bundle doesn't provide a free copy of Don't Starve.

So I guess you can't get Don't Starve 1 copy anymore. Just tell you the information I know, probably someone has it(like me).
