I've spoken to the cat. Freed the wizards helpers from the jail
and poisoned the cheese. But when i put the cheese down and kill a rat, nothing happens except that my journal updates with a text saying that all the rats are hiding from me and i need to find a way to draw the rats out of their holes..
I must've reloaded 10+ times now trying to do it different ways and nothing helps.
Is this a known bug or am i missing a step, like talking to someone?.
