The feature to prevent the fat and muscle of non-played sims changing was sometimes causing simulation lag, where sims would freeze in place for a moment when attempting to change action. This update implements the feature in a new way that should eliminate this lag.

Changelog:

• The 'No NPC Fitness Change' feature should no longer cause sporadic simulation lag.
• Changing the 'No NPC Fitness Change' setting now requires restarting the game to take effect.
