Bought gift - cant see it in inventory

Reload steam. I had that once.

Piece of advice: buy the game and make sure you got it before making the giveaway. Worse things could happen, I know a person that made a giveaway for a game on sale, and when the giveaway ended, the sale had been removed due to it being an error.

well, sent ticket to steam support ;p hope they will do something

I had this happen once. Sent a support ticket to Steam. Don't know if that did it or someone buying a trading card "updated" my inventory, but I noticed it showed up at that time.

Same thing happened to me. Bought 3 gifts yesterday, they still havent shown up in my inventory. Did your DLC show up yet?

Did some research and apparently adding redeeming an item from your inventory will make the missing items magically pop up

Edit: I can confirm this fix worked. I activated a game and the 3 missing ones showed up.
