I didn't see this combo listed in the Prince or Fool sections of the known bugs.
If you Prince a Fool, there are two paths:
1. You already have the Lost In The Woods. In this case, it asks you (correctly) whether you want to discard for a boon or play the Fool first. It goes as you would expect.
2. You don't have Lost In The Woods. In this case, it does the wrong thing. It plays Fool, presents you with three boons, but then afterwards, it asks 'would you like to discard for a boon?' as if it were the beginning of a new turn. Based on the language on the Prince card, it doesn't say BEFORE your turn, it says "At the start of your turn", so this feels like incorrect behavior to me.
