Giveaway won no longer showing

Yesterday I won Darwinia soundtrack and I have been given the key. I activated the key and all was working.
However tonight this is no longer showing as a won giveaway. I wondered what happened to the giveaway?

I checked my list of entries and all I see are won and received by others.

I just checked Steam and this is still showing the DLC and I ran the install and I have access to the Soundtrack.

I wonder if it has been re-rolled and the new winner got a key too? Or maybe it has been deleted? But if it has been deleted, why would someone do that if he has given the key and it worked?

Sadly I can't remember who it was. We added each other in Steam and I removed him from my friends list after we had a little chat and I confirmed the key worked and marked it as received.

Curious....

Personally I think the giveaway has been deleted. As the giveaways I see in my closed entries do not have names that ring a bell or mention it will be sent via Steam.
