Why won't Sara on HorseIsle give me a pie to take to Candide for the quest Candide's Golden Sheep?

In HorseIsle, Sara won't give you a pie for Candide's quest because you likely haven't completed the necessary prerequisites or tasks required to unlock that item. The game often has specific requirements that need to be met, such as reaching a certain level, completing previous quests, or having particular items in your inventory. Make sure to check your quest log and ensure you've fulfilled all conditions to receive the pie.
