Phases System

Toddlers, children, and teens can now experience phases that change their personality.

Phases are moodlets that temporarily change one of a sim’s traits. Phase moodlets last for 2 days, with a 48 hour cooldown between the end of their most recent phase and when a sim is able to experience a phase again.

Each time a toddler, child, or teen sim wakes up, they will have a chance of experiencing a phase. The base chance of experiencing a phase is 20%, but this chance can increase or decrease by 5% based on the factors/moodlets listed below:

Increased Chance

- Witnessed Divorce
- Witnessed Death
- Witnessed Betrayal
- Heartbroken
- Stuff Taken
- Stir Crazy
- Abducted by Aliens
- Embarrassed
- Lost a Friend
- Negative Mood
- Has Enemy
- In Trouble (Generations punishment system)
- Stress Moodlets (Stressed, Strained)
- Has No Friends Outside of Household
- Adult Household Member Dislikes Children
- Negative Relationship with Adult Household Member
- Negative Prom Moodlets (Ditched, Got in a Fight, Denied)
- Negative Celebrity Moodlets (Got Recognized Negative, Publicly Disgraced)
- Negative Job Moodlets (Overworked, Fired)
- Negative Social Moodlets (Lonely, Desolate, It’s Like I’m Invisible, Misunderstood, Need to Brood, Rejected)
- Negative Romance Moodlets (Rejected First Kiss, Betrayed, Dumped by Text, Rejected by Ex)
- Punishment Moodlets (Got in Trouble, Got Put in Timeout, Privilege Revoked, Grounded, Prank Backfire, Caught Pranking, Caught After Curfew, Detention)

Conflicts & Known Issues

Because this mod temporarily changes a sim’s traits, your sim may become unclickable if you also have Branndo10’s DrugLord mod installed at the same time. (Thank you to MonocoDoll for the heads up!)

Otherwise, there shouldn’t be any conflicts.
