Poking aroung with traits and sim types, I made a couple discoveries:
- The Immune To Fire trait, does not stop an inventor sim from randomly catching fire and burning to death at the table. I thought I had the brilliant solution to prevent that frustrating little event, made a Firefighter, leveled up to the required level to pass on the related traits, and tested them through normal methods. The sim had the trait. Thinking I had beaten the system, I set my supposedly fireproof sim to inventing and walked away to get a sandwich. I came back to one less sim and a pile of ash in front of the inventing table. Dad was off at work, so was not there to extinguish Jr.
-In any normal situation, a mummy is a pile of ash waiting to happen when it comes to fires. A mummy with a penchant for playing with welding torches however, does not catch on fire OR get electrocuted. A typical sim, with or without the Lucky or Unlucky traits, can catch on fire up to several times an hour, separated only by the time it takes to jump in the shower and get back to inventing. I had a mummy sim sitting around and decided to give them a try. Ten levels of invention skill leveling later, not one single spark, even with Unlucky.
As a general rule, all of my inventors and sculptors are unlucky, to prevent the loss of hours of work to a random ignition when I am not paying attention.
