Time anomaly

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

Time Paradox Sickness
There is a chance that after extensive use of the Time Portal, a Sim will acquire a Moodlet named 'Time Paradox Sickness'. This moodlet is the first stage of Death by Time Anomaly. It lasts 4 hours. If the sim with the moodlet doesn't admit themselves to the hospital with Time Paradox Sickness, it will be followed by another moodlet, 'Blinking In and Out of Existence', which lasts one day. When that expires, it is followed by the last moodlet of the Time Paradox Sickness, '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
If the affected sim has the 'Blinking In and Out of Existence' moodlet, they will occasionally have an action with the same name in their queue. While performing the action, they will witness an arm or leg vanish and reappear.

On the last stage of the sickness, the Sim may again get an action in their queue, called 'Do I even exist?' along with the corresponding moodlet. 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 will depict a Time Anomaly victim, partially faded.

An afflicted sim can admit themselves to a hospital with Time Paradox Sickness.

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.
 * There is a Lifetime Reward called 'Portal Immunity' worth 5,000 points that prevents Time Paradox Sickness.
 * The sim will have a holographic gravestone projection regardless of whether they died in the future or not.
