Okay, I have the quest in my quest list: "The Secret Ingredient". I have 5 "Speckled Poison Sacs" in my main backpack. When attempt to "Toggle Quest Item" and highlight Sac, I get this message "That item does no match any of your quest citeria". So bascally Petrus does squat for me after I died 3 times getting those 5 Sacs! Please enlighten me...what am I doing wrong?!?!?!?!
