Hello! First of all, I just wanted to say... I have been enjoying this mod. However, I have discovered a very specific issue when living in one of the houses that is located in Finchwick. Sims in my active household are being assigned to be the Gossipers required for one of the Errands. Which fills and freezes all their motives and also causes a whole host of odd issues; they can't enter their own house, they can't interact with laundry objects, they can harvest/water/weed but only one plant at a time, they can't throw away trash... and possibly other issues as well that I haven't positively linked to this condition. 
Hi there! That particular role has been troublesome in the past, but I can't think of any reason why it would be applying to your Sims. Is there something during your gameplay that triggers it, like travelling between lots, or does it seem to be random? For better troubleshooting, please join the Discord server and we can get more information about the situation there.
