Another question that came up:

What happens to the chaos bag when you start a new campaign with the same group of investigators? Do you start all over with the new chaos bag suggested by the rules, or do you keep the old one with all added and/or removed tokens?

The rules, as far as they exist for this, just say carry over each investigator's deck, trauma, and experience. I don't think the chaos bag carries over. The tokens are in the bag are such an integral part of how each campaign plays, I don't think you would ever want to play a campaign with the tokens from a different campaign. I've heard people say bumping up the difficulty of the bag is a good idea, though, since the decks are powered up, even with some trauma.

EDIT: This is actually covered in the FAQ now: "The chaos bag is reset. This includes all additional chaos tokens that were added to the chaos bag throughout the original campaign."

Whoops! We're having a situation where the original team of investigators has already been killed, went insane or retired over the course of the game and the current chaos bag is too difficult for the XP we have. I think our best investigator is somewhere at 15 XP, which is very little, considering that we're going into the 19th scenario (Dim Carcosa).

Great game
