When I'm playing in the University (I have Ep1 + Ep2) I notice a lot of NPCs will come to the house and my sims won't be able to interact with them easily. Every time I click to interact with them, my sim will follow them around for a while or just stand there, and the interaction will disappear from the to-do list.
So- I selected them using the Inseminator selector and found that these sims had the secret society icon in their to-do list, and the hover says "hide".
Any hacks out there to get these annoying NPCs to stop "hiding"??
