Sanctum: Exists in your account

try force-syncing your steamgifts acct: http://www.steamgifts.com/sync

Wait for a while, then resync.

i get that too, already re-sync, but still exists :(

"This is a Public Service Announcement. If you actually play the game you have to wait 2 weeks for it to be removed from your recent playtime games, and once that is done, sync and it will be gone. Those of you in the thread who didn't play the game it should be fixable by synching after the weekend is over. For future prevention always sync during the middle of the week to prevent accidental autosynching on a free weekend."

It depends when you had it for free... but you might want to wait for a bit.

Same problem here. I've bee re-syncing my profile almost every day since the end of the Free Weekend, doesn't help.
I've read in another topic, that it's a common problem for every Free Weekend game and that it might take from 8 hours to 2 weeks for the game to vanish from the profile.

What to do with Dota 2 with problem like that? I want to join to giveaway, but it's already exist in my acc, but it's version without playing option.
