The Sims 4 Enchanted by Nature Ailment Update will be released on August 19, 2025, bringing major fixes players have been waiting for, and it brings some long awaited changes that many players have been asking for. Right from the start, this update focuses on giving Simmers more control, making ailments less intrusive while keeping the gameplay fresh and rewarding. Whether you enjoy managing challenges or prefer a smoother storytelling experience, this update will have something for you.
What Are Ailments in The Sims 4 Enchanted by Nature?
Ailments were designed as special conditions that affect Sims in unique ways. Some come with drawbacks, like strained relationships, while others offer hidden benefits, such as skill boosts. For example, the Greenie Meanie ailment reduces social success but improves Gardening skill, a perfect twist for plant-loving Sims.
The intent behind ailments was to add depth to gameplay, encouraging players to adapt and find creative solutions. However, many players felt ailments appeared too frequently, disrupting the flow of their Sims’ lives. This update directly addresses those concerns.
What’s Included in the Sims 4 Enchanted by Nature Ailment Update?
1. Reduced Frequency of Ailments
Before this update, ailments spread too often, leading to frustration. The new patch rolling out on August 19 will reduce the frequency even further, giving players more breathing room.
2. New Ailment Spread Toggle
The biggest feature in this update is the Enable Ailment Spread toggle. Found in Game Options > Pack Settings > Enchanted by Nature, this setting allows you to completely stop ailments from spreading between Sims.
- Enabled (default): Ailments can spread naturally but at a reduced rate.
- Disabled: Ailments stop spreading, though Sims already affected will keep theirs until cured or resolved.
3. Balance & Imbalance Options
Sims that become Very Imbalanced can still develop ailments, even with the spread toggle disabled. However, if you’d rather not see ailments at all, you can also disable the Enable Balance & Imbalance toggle, removing this trigger entirely.
4. Impact on Fairy Sims Abilities
Fairy Sims’ abilities are unaffected by the update. You can still use their Cure or Apply Ailment powers. This means that ailments can remain part of storytelling if you choose, even with spread turned off.
5. Changes for the Naturopath Career
If you’re pursuing the Naturopath Career, clients will continue to visit with ailments that need treatment. This ensures that gameplay tied to careers and skills isn’t disrupted.
6. Apothecary Crafting Remains Important
Crafting cures at the Apothecary Table is still vital. Players can make remedies to treat Sims or sell them for profit, keeping this activity relevant no matter the settings.
7. Storytelling Flexibility for Players
The main goal of this update is flexibility. If you enjoy chaotic gameplay, keep ailments spreading. If you prefer a calmer game, disable the spread for smoother storytelling. This balance gives Simmers more agency than ever.
How to Adjust the Settings in Your Game
To toggle ailments:
- Open Main Menu > Game Options.
- Select Pack Settings.
- Scroll to Enchanted by Nature.
- Toggle Enable Ailment Spread on or off.
- (Optional) Disable Balance & Imbalance for a fully ailment-free experience.
These options can be switched anytime, letting you experiment and find the style that works best for your save.
