Invisible fire

Fires that doesn't even exist start somewhere in the house. It's like it doesn't exist but we can't save the game and leave... We can hear the fire but there is no fire, the Sims don't even react and the firefighters don't do anything. It's been the 5th times since 2 days... Each time I have to leave without saving... 🫠🫠🫠🫠
