I spent the weekend with no wifi and i knocked out ALL OF THE CHARACTERS with their special item, and it shows so on the [Esc] screen.
when i knocked them out, the achievements did not pop up, and i did not receive my items on Team Fortress 2.
I now have Wifi and the items have not shown, nor the acheivements.
Poker Night 2: I have also not gotten the Bloodhound from getting Sam's banjo from bounty.
this was ALSO completed when i did not have wifi.
Hope you can help.
