I was testing some things and summoned the social worker. She apparently gave up trying to fit all the babies into the van. Another social worker eventually showed up but then just disappeared after a while.

FLAGABOO!

I've had similar problems. Happily, one time two social workers left with a few babies, but the rest of the toddlers and kids never left, and when I left & re-entered the lot they were all controllable.
AND THAT DOG! eeeuuuu

Having just put the shopping on the table (because her mum Lianna was blocking access to the fridge, playing red hands with Julian Moltke-Jones), Gill Cuthbert discovers that she can't pick it up again to put it away.

In the end I had to help her out, by moving the shopping to the kitchen counter. She was able to able to pick it up from there, and finally put it into the fridge where it belonged!
