The Sims 4 Update: Official Patch Notes (Sep 22nd, 2026)

Key Points:

• Sims now walk faster during the "needs to pee" animation when bladder needs are low, and they face each other during conversations to enable eye contact.
• Autonomous behaviors have been refined: Sims who dislike gardening, dancing, fitness, or phones will no longer perform these activities autonomously, and Sims will avoid lounging outdoors during rain or storms.
• Various interactions and UI elements have been improved, including fixing the "Negotiate a Bonus" phone interaction, preventing the expanded Buff View panel from closing at high game speeds, and resolving issues with Sims getting stuck in interaction queues.
• Fixes address gameplay bugs such as Sims from inactive households attending university classes properly, preventing rapid romantic satisfaction decay, reducing excessive snow-related autonomous actions, and correcting Sims' routing and positioning during toddler book reading.
• Numerous technical and stability improvements were made, including fixes for crashes related to pools and build mode transitions, better handling of infants on loads, improved roof trim clipping, and resolving asserts in visual effects and Create a Sim panels.
