I'll see if I can find the save later this evening.
I see that the thread you merged me with mentions a rug, but the rug seems irrelevant. In my save there's no rug nearby, it just seems to set fire to the nearest object. (The coffee table in my case, and then the couch right behind it.)
@z4a0c6gvml4j Yes and the auto-light seems to exacerbate the issue, as I can't put out the fire 😂 Ended up buying a new fireplace after it happened for the fourth time. Thankfully I had sprinklers and no one died. (I did have a sim die right before a fire set out though, Grim Reaper helped put the fire out before the sprinklers set in. Kind of funny but I'd still rather not burn my couch and table down twice a day)
