Re: fire

There are a few things that I can think of that may be causing this.

1. If there is a lit fireplace nearby

2. If there is a lit incense holder nearby (Spa Day)

3. If there is a space heater nearby that is on (Snowy Escape)

4. The temperature is very hot and your sim is burning up (Seasons)*

5. Your sim is a vampire and they are burning in the sunlight (Vampires)*

*those last 2 shouldn't be it though since your sim is indoors, but it could be a bug
