This clay bug is driving me mad. I was able to have my sims move house with the funds I'd made just from selling clay. It's constant - I'll clean out the clay from their inventories, switch to another sim and by the time I go back there's like 10 clays in their inventory again. They're also constantly stopping to play with the EL tablet autonomously. Even repealing and ultimately switching off NAPs didn't work. So yeah, I'm gutted that the patch didn't address the clay bug. I don't really use mods, so I'll just be playing in different saves until my affected sims are given a cure from this madness.
