It appears that Picnic in the Park no longer exists at all as far as being a pre-ordered picnic that you order in the morning and pick up later in the day, with hot food options such as rotisserie chicken and sides.
You can still get the Tier 2 sandwiches, chips, and drinks from a grab-and-go at the Beastly Bazaar and assemble your own picnic. But you can no longer pre-order one, the chicken and ham are not available, and no hot or cold sides.
