Hello again! I can't deliever the gift to you because can't check you for not owning any of this DLC packs. It's because DLC doesn't really work well with the Steam API, so any giveaway that involves DLC can be entered by those already owning it.

I know 2 ways to check that (basically list of friends with certain product / attempt to buy a product for a friend and fail if he already own it), but both of them requires me to add the winner to friends.

Maybe support have another tools, so I can ask them about it, but it'll take more time than my manual work (days vs minutes).
Meanwhile to resolve this situation faster you still can add me to friends - I'll check DLCs and then remove you as you wish.
