When you reach the part when Gary told you that you can try the MP, and that he will give to you a free starter pack (Adventurers), if you choose to not use this starter pack as your MP party, you stay in the Starter Pack Store, and the Adventurers starter pack is still free. I tried a couple of time this bug before exiting the Store, and now I have 3 Coraline, 3 Tineva and 3 Hurthin fully equipped!
I'm pretty sure this is a temporary client side only glitch. If you go into the deckbuilder or a game I don't think you'll see those extra characters or items - correct? I'll fix it up anyway, of course.
Unfortunately not. In the deckbuilder I have 3 of each to choose for my party, with items and everything else. I'll try to make a party and play, but I'm pretty sure it's not a glitch. EDIT: yes, I can make a party and play. Definitely a bug.
Nope. I had no pizza left. It was when Gary ask you to try the MP, giving you a Starter for free. As stated before, choosing to not use the starter pack as your multiplayer party, you stay in the screen with the Adventurers starter pack with the button still saying "Free". EDIT: with Jon's help we figured it out. It's only a glitch, who let the "Free" button on the Adventurers pack even after you took it for free, until you exit the starter pack screen.
