Steps: How can we find the bug ourselves? Have a fire start from a fire place, get the fire notification, sims panicking and fire alarm going off, the fire is invisible and cannot be extinguished.
What happens when the bug occurs? My sims get back to their home lot from a restaurant, and I immediately get the fire notification. Furniture and floor starts getting burnt as it would in a regular fire, but I can't see the fire or click on it. I can click on the furniture and I get the extinguish option, but when I click it my sim does the 'Can't reach' animation.
What do you expect to see? The fire should be visable and my sim should be able to extinguish it.

I've seen this happen in a video and I've had the problem before as well, but both times the sim has been able to click on the floor and extinguish the invisible fire. I am not able to remove custom content to see if that fixes the problem as I would have to close the game without saving because of the fire on the lot. I have had problems with sims not being able to reach things in the apartment before, but not in this room. I moved any objects I could without going into build mode, but nothing changed.  I understand that I will have to close the game without saving if I can't fix the problem.
