Autonomy issues

I'm trying to rule out the cause. So basically this household is full with 5 sims, 3 cats. House is big in Brindleton Bay with lots of decor and items around. I'm playing in laptop. Oftentimes when I tell them to do something they will either 1) cancel it or 2) never stick to it. My other households does not have this issue. 

Is it because of the house size and pathing issue? Is it mods? Why isn't this issue apparent with my other households? I tested without mods and there's no difference. Sorry if this post is kinda unclear...
