To find those hidden people in the cellar I spoke to Jinxika and then I lured some mice with poison cheese, killed the Rat King in the tavern cellar, hanged Ratcatcher and Jinxika told me the refugees location. I didn't tell her to hide from the rats. Later, when I completed all the quests in Hunter's Edge and instigated the final showdown with orks and humans, those bloody orks killed Jinxika in the first turn! And what's more, my characters said that the "feline threat is eliminated" and that rats should be pleased ss if I'm still doing that refugee search quest!
I think she should have just dissapeared after I saved those refugees, there's no point in hanging around Hunter's Edge for her anymore after that.
