Time anomaly

Time Anomaly is a form of death introduced in The Sims 3: Into the Future.

Time Paradox Sickness
Occasionally after going through the Time Portal, a Sim will get a Moodlet called "Time Paradox Sickness". This moodlet is the first stage of Death by Time Anomaly. This moodlet lasts 4 hours.

It is followed by another moodlet, called "Blinking in and out of Existence". It lasts one day. When it expires, it is followed by the last moodlet of the Time Paradox Sickness, called "Do I Even Exist?" This moodlet is -30. It is the last stage of the Time Anomaly, and the expiration of the timer will result in death.

Effects
During the "Blinking in and out of Existence" moodlet, the afflicted sim may get the "Blinking in and out of Existence" action in their queue. While performing the action, the Sim will witness an arm or leg disappear and reappear, and will be alarmed.

On the last stage of the sickness, the Sim may again get an action in their queue, called "Do I even exist". During this action, they may completely disappear and reappear.

If the afflicted Sim does not go to a hospital, they will die by Time Anomaly. The dead Sim's gravestone, when mourned at, will project a holographic image of the dead Sim.

A Sim that has Time Paradox Sickness can have it cured at the hospital.

Trivia

 * This death resembles Marty McFly in the high school dance scene of Back to the Future. During the scene, as his mother gets taken away from his father, he begins blinking in and out of existence similar to a Sim with Time Paradox Sickness, which ends when the paradox is fixed.
