This is happening in my game now, too. My (spellcaster) sims are at the Humor & Hijinks Festival. As soon as they order food, they hop on their brooms and fly all the way across the street to the bar/art center building, an NPC takes their food, and then they slowly walk back to the festival to get food that is no longer there.
After trying to order food 6 times (consecutively) and having this happen EVERY time, I finally had to give up and cheat my sims' hunger needs so they didn't starve to death while squandering their life savings to feed the entire NPC population of San Myshuno. That ended up being the whole festival experience.
I guess I'm off to find a mod that unlocks those recipes, since learning them is only possible by eating food it's no longer possible for our sims to eat.

From the looks of this thread, it appears this has been an issue for THREE YEARS.
As much as your customers have paid for this game and all of the DLC, we deserve a product that actually works.
Fix it.
