Please use this thread going forward: Upgraded fire-proof objects catching fire a lot | EA Forums - 5037638
I know this is old, but I'm having this issue in my current game, all updated to latest patch and expansion.
I have a relatively expensive fireplace in my Sims house, and the floor in front of it caught fire several times within a few weeks of putting in the fireplace. Most of the time it spreads to the coffee table that is about 3 tiles out before I get it put out.
Upgraded the fire to fireproof, and there have been 3 more similiar fires since, over about 8 sim weeks.
I'm going to try replacing the hardwood floor with stonework for all the tiles under and immediately around the fireplace to see if that helps stop the fires. It's bad, the fire that just happened almost got both my toddlers this last time.
Having the same problem. SO MANY FIRES. I don't even light the fireplaces anymore because immediately after I do, a fire starts. Objects aren't even that close to the fire, may 2 tiles away. It wasn't a problem before, and my sims always had the fireplaces on 24/7, same house, same objects around. Then all of the sudden everything started lighting on fire one day. The rugs, the chairs, the ceiling lamp, something on the mantle. I can't find a newer thread on this, but it's been pretty annoying.
