EDIT: The 4 Anise I had in my inventory were from the Jungle. When I found an Anise in Forest, which was where I was experiencing this problem, she accepted it. So it would seem that she's ignoring ingredients found in different terrains.
Here's the witch encounter:

This isn't necessarily a bug, but it doesn't quite make sense. In theory, wolves with an Excellent howling rating would always be able to beat the undead wolf in howling right? Well I've had wolves with any rating from Below Average to Excellent beat him and wolves from Excellent down to Poor lose to him. So I don't quite see how it's fair. In this event it's more difficult to earn the currency than the other events so how are I supposed to get 700+ brains if my wolves have a random chance of winning or losing the most frequent encounter? Like I said, I don't know if this is a bug or not, but could it possibly be changed to make it more fair? I just don't understand what would give a wolf a better chance of beating the undead wolf in a howling contest other than their howling rating.
