Sims no longer eat leftovers?

One more note on this bug. When I play a family actively I somehow manage to catch them and prevent cooking most of the time so it's not that bothersome... But today I've found another thing which is much more disturbing for me since I'm playing rotationally. Currently I'm playing with a sim who was separated from her family household to go to Uni. So she's my active household now and her family is inactive in Willlow Creek. Her Dad called and invited her to visit. I've accepted and what I've found is a family of 4 sims literally starving and cooking non stop. All their kitchen was filled with dishes, their grill at the backyard was all surrounded by dishes... And all they have their hunger motive drained...

But my main point is - it was inactive family! I do not think they suppose to cook at all not to mention non-stop in the background when I play another family in another hood. But it looks like they did! So what I'm thinking now - could this bug also be a part of simulation lag? Also now I'm pretty scared to visit anyone in order not to provoke them starving and cooking while I can't control them.
