I had a pretty ridiculous thing happen to me in game just now. I generally lock my child Sims' rooms to them alone so that visitors and family don't hog their toys/computer/etc. My child sim was experimenting on his potion set & set it on fire. Being a child, he could not put out the fire. No-one else could put out the fire either, as his room was locked (& I couldn't unlock it because the interaction was not available due to the fire). Of course no one could do anything at all since there was a fire on the lot. Eventually the fire put itself out.
Anything like this happen to anyone else? Any solutions? Is there a cheat that can be used to allow normal interactions with objects during a fire? I could of course just not have any objects that can cause fires in child-only areas, but still.
