We were playing Infernal Machine, hoping to get organs to make hellfire ring
Anyway, after ending our run, my friend forgot to buy the Hellfire Ring Design, which is only available from Squirt the Peddler in Act 2.. instead of quitting the game, change quest to go Act 2... I suggested we just talk to Tyrael and the Caravan guy and we can go Act 2..
Spoke to Tyrael, but surprisingly, the Caravan guy does not have the dialog option for us to move on to Act 2 no matter what we do....
In the end, we have no choice but to quit the current game... think this shouldn't have happened..
