How else should I spark a fire in my home? The mac and cheese won't burst into flames despite a level 0 chef and a cheap oven. I hit the cancel so that it would stay on the stove and keep on cooking. I also surrounded the thing with rugs.

Edit: Nobody in the home is a firefighter and I NEVER buy the Fireproof homestate LTHR.

Haha, pyro, huh?

What about trying to cook something in the oven, like waffles? I know that my Sim would constantly start fires because they'd put the waffles in the oven then go take a nice long two hour shower...

Fireplaces. And lots of them! If I want to start a fire I usually make a small room, fill it with the cheapest fireplace (use moveobjects on to fit more,) and then add layers of rugs.

Yeah, definitely fireplaces. For me, even the expensive fireplaces set things on fire if left on for too long.

Is your sim a firefighter? haha...

Are you sure you don't have the "Fireproof homestead" trait, your sim or your sim's parent wasn't a firefighter?

Slow cookin' is good cookin'.

Speaking of fireplaces, I always enjoy the fireplace in the French 'base camp' because if lit, it usually catches fire every few hours or so.

I didn't get a fire till I had my sims light the fireplace too. Left it on overnight while they slept (I forgot to let my hacking sim turn it off) and swoosh! The place lighted up like a roman candle.

Ifr I recall correctly, food being prepared by a Natural Cook never burns, even if they're AWOL or have low skill level.

Unlike the previous 2 games, low skill cooking while tired doesn't automatically mean the house burns down, even if the food is abandoned. It just means disgusting quality food. It takes a critical failure to ignite it, and that isn't affected by whether or not it was abandoned. If you are trying for a fire, cook -lots- of mac and cheese. Not the same pot for 4 days. And cook while your sim is tired, hungry, stressed out, lonely, stinky, and needing the bathroom. A yellow or red plumbbob will help cause fires, too.

Oh, that is what is needed for a stove fire. I care way too well of my sims it seems. Time to get mean.

I left food in the oven by accident and then went to work. Within a few sim hours, the place was on fire. My sim was in a good mood, it was a somewhat cheap stove but the food was left by a "natural cook" sim. I don't know if it was just a weirdo freak thing or anything, if that helps though.
