Gastrobury's bonus doesn't seem to work.

I annexed Gastrobury. In the territory description it says that the reward for doing so is doubling the time you have a positive moodlet for eating food. That has not happened for me at all. I made a bowl of Hunter's Stew and each time I eat from it, it still only gives me the default 6-hour moodlet. I made a Venison steak from the spit, and it only gave me the usual 12-hour moodlet like all other spit-recipes do.

I don't know if that's a bug or what.

Have you done the Gastrofest or Bust quest? 

I know I've done this, and I can't remember if there was a change in the moodlets after the quest.  Somehow, I don't think I noticed much difference either.

I'm afraid so. Paid the RPs to ally with them, then immediately did the quest to annex it. No change to the food that my sims eat.

Agreed. I think there are a few bugs with the foreign territories unfortunately but at least the Advorton benefit namely -1 QP on all 3-4 QP quests works for me
