[EBN] Natural Living Skill Not Working Autonomously

I've encountered a bug or a major oversight by the Sims 4 team.

My sim has maxed the natural living skill, but despite this, she won't autonomously summon a privy bush, sleep on the ground or eat harvestables to satisfy her needs even though she possesses the skill and necessary items. By default, she will continue to suffer without a toilet, bed or fridge. 

Why? This makes the skill obsolete. I bought Enchanted by Nature for the natural living skill alone, so this is very disappointing.
