First Giveaway help [Solved]

How do I tell if a winner received my gift? Here's a more specific description of my problem.

I won a copy of The Ship complete pack and with it, I got another copy to give away to someone else, but had to wait a month for it to become tradeable, which I did. I created the giveaway yesterday and have been given a winner. So I send the gift to their e-mail associated to their steamgifts account. In my steam, it says that The Ship is being sent to the winner and is waiting to be received, so I've been waiting. Now I check their steamgifts profile and they have created a giveaway for The Ship which is now closed because of accidental creation, so I figured they got an extra copy with it to give away as well. But then I check on steam and I still have a copy of The Ship complete pack as a gift and it doesn't say it's still being sent to the winner anymore. Also, they haven't tagged the gift as received on SteamGifts. What does this mean? Does the ship come with infinite copies to giveaway (yes, i know it sounds ridiculous to me too), or have they rejected the gift on steam and I should request a new winner?

EDIT: The winner has finally accepted the gift and tagged as received on SteamGifts.
