Firefighters don't do anything

My sim living in the new world in the Enchanted By Nature pack started a fire at the stove. The fire alarm sounded and the fire fighters showed up. They stood on the sidewalk and never came in the house! My sim ended up catching on fire. I sent her to "Extinguish Self" and still they stood on the sidewalk as the kitchen was being engulfed in flames. I sent her to put out the fire which she managed to do. When the fire alarm stopped and the fire was put out the fire fighters standing on the sidewalk poofed and disappeared. I have no mods or CC and never have.
