@Marinuttonen To be sure, it's your Sims that set it on fire while using it not the specters ?
The fireplace has always been a bit of an issue as reported here. https://answers.ea.com/t5/Bug-Reports/OPEN-Upgraded-Fireplace-catching-fire-a-lot/td-p/6390403
It's definitely the fireplaces, some of them I've noticed started after my vampire sim flew into the room as bat and the autolight happened.
I've had specters setting things on fire too, but that's all good fun.
I've also seen the stoves with "heat sensor" catch fire multiple times on my haunted lot, but the fireplaces are particularly annoying as it happens frequent enough and they're supposed to be 100% fireproof.
