You didn't mention if the food is custom content or not. I only mention this as I download lots from a site that builds a lot of models not necessarily built to play or live in them but to enjoy the model building of real places etc. I know this is a custom world however is it custom food? I have several custom dishes that are placed on surfaces that do that, I have to remember not to put them on community lots like the ones I downloaded. Or is this a custom table or counter? Some of those may not be actually cloned from a counter or table but something else and cause a jump bug lovely as decor to look at and function sort of like a counter or table but may cause some glitches. Just making some suggestions. Or one last thought if not a routing issue, do you have custom plates in your game? those also can cause this jump bug reset. ETA: The world is probably fine the problem would be in or on the lot.
