Re: Karma in Sims 4?

@Ozaeki the only time The Sims had Karma in it was from an older version,  either The Sims 2 or The Sims 3 (I think it was TS3), but for the console version only.  With TS2 and TS3 the console version were completely different from the PC/Mac versions!  I don't remember which one it was, but one of the console version from back then did have Karma Points , or Karma Powers, or something like that. 

And while the Sims 4 has never had karma in the game, we do have a new Sentiment system and a new Lifestyle system.  I I don't know if there is anything like what you are talking about with the new system since I had to take a break from playing TS4 to do some real-life stuff 😞, and so I haven't been able to experiment with that new system much, unfortunately. ☹️  However, this does not sound like the few sentiments and lifestyles I encountered when I have gotten a chance to play since then.  
To be sure, I checked with Carl's Sims 4 Guide Lifestyles List - The Sims 4 Snowy Escape Expansion Pack Guide (carls-sims-4-guide.com)

  and Learn About the New Sentiments Feature in The Sims 4 (carls-sims-4-guide.com)
But none of these seem to be anything like what you are talking about.  I only include them in case I have missed something.  

That being said, fires do happen often in the Sims!  I do not like my Sims to have extra-marital affairs, yet they have often caught on fire ! 🤭😅  I think that what happened in your game  was just a coincidence! 😆😉
