Information on some of the rare foods quests was unintentionally left off of the patch notes. Sorry for any confusion!
Quest 'Rare Foods: Food For the Road' added to Fellea.
Quest 'Rare Foods: A Spicy Snack for the Famished Miner' added to the Famished Miner.
Quest 'Rare Foods: The Brains of the Outfit' added to Xenex the Blind.
Quest 'Rare Foods: Dinner? Impossible!' added to most Imperial Vaultkeepers
All quests are level-based and should be done in order.
