I had a similar'ish (more minor) "jump bug" with sims trying to eat at a picnic table in a crowded room. They'd put their plate down and warp to the other side of the table or to the end of the same bench--then they'd have to stand up and try to walk over to where their plate was or they'd cook more food.
My temp fix was to hand-of-god the food to a different place on the table after the hungry Sim quit mind-controlling it, but I ended up having to make more pedestrian pathing space in the room.
I had this bug when my favourite sim had a baby. She constantly kept flicking up in the ''baby in arms" position. I reset her, but it did nothing. It's really, really irritating.
I had this bug too and it sucked. I was able to fix it by typing "resetsim Incubator Deluxe" where Incubator Deluxe was Sim's name, because just having Incubator targeted and typing resetsim wasn't enough.
