Re: Caterer made foods are not leftovers
I think the larger problem might be “caterer made foods are still owned by the caterer” and not by the party’s host who paid them to cook. So you can’t drag them to your sim’s fridge or tell your sim to put the platter in their inventory to take home. I’ve not noticed the leftovers bug specifically, but I don’t think I’ve ever had just a caterer’s food in there except for when a member of the household was the caterer.
