What could POSSIBLY go wrong :D?

Has this ever happened to you? The party is moving along nicely, everyone knows their part in the plan, then SUDDENLY, everything is on FIRE. Well, we have the solution for you! Actually.... no. That is a lie. But! We DO talk about how things can go badly, and offer a few small words about how to handle those situations. Additionally: As Banjo says in the cold open, Ratkin are organized by "Aspects" and not "Plagues". Le sigh..
