Problem with Games in Your Account

I believe they just had a free weekend for it

If you play a game on a free weekend and sync meanwhile it will take about two weeks until you can enter giveaways for it again. Seems like it's Steam's fault and not steamgift's. At least that's what I've read.

Thanks!

I didn't play it during the free weekend but I have the same "exists in your account" problem.

Free peacock

That is why Steam adds the free weekend games in the game libraries. SteamGifts retrieves user's game libraries to check what a user owns. Next time a free weekend is announced for a game you are interested, sync manually your SteamGifts account before the game is added in the library. Or else, after that a scheduled sync occur, you'll have to wait up to two weeks to enter one of these giveaway again.
