This next game update is set to be released on February 3rd, as the blog says: “On February 3, we’re rolling out an exciting Base Game update that introduces expanded and improved functionality for family trees, genealogy, and relationship data”.

Laundry List: Upcoming Bug Fixes – Jan 27, 2026

Hi Simmers!

Welcome to the Laundry List, where we share the top community concerns that we’re currently investigating and hope to resolve. If you’re hitting crashes, infinite loading, or missing lots, please read our post here to see how you can share affected saves so we can gather some critical information to aid our investigations.

The Sims Team

Upcoming Update for Mod Users

On February 3, we’re rolling out an exciting Base Game update that introduces expanded and improved functionality for family trees, genealogy, and relationship data. These updates enhance how Sims’ family connections are tracked and displayed, and we’re looking forward to sharing more details with you very soon via @TheSims on X and in The Sims 4 Newsroom.

Because this update makes changes to core game systems, our testing has shown that some mods – particularly those that extend or interpret family and relationship data – will be affected. This could appear as missing relatives, unexpected relationship changes, or family trees that don’t reflect what you expect. In rare cases, these issues could negatively impact your save.

If you use mods that involve lineage, generational gameplay, or complex family rules, we strongly recommend removing them before the February 3 Base Game update and waiting until the creators confirm compatibility.

Thank you for your patience and for giving mod authors the time they need to update their work, helping ensure your Sims’ family stories continue smoothly

Mod creators, in an effort to assist you in updating mods that touch genealogy as mentioned above, we’ve provided a list of Python changes to you for this Base Game update over on the EA Forums here.

Save File Investigation Update

Improving save file integrity continues to be a top priority. Since our dedicated investigation started in September, we’ve delivered preventative solutions for a range of issues, both player reported and ones we’ve identified through our investigation. We’ve also shipped improvements to core systems, like slowly rolling out changes to Scratch Files and rental cheats, to support this work. For remaining issues, we’re awaiting further information from players experiencing them to be able to investigate further, and will continue to monitor for any new player reported issues.

We’re now ready to shift our focus from investigations to longer-term prevention, and with that, will provide future updates via the Laundry List instead of a monthly standalone post. When these changes ship, they’ll be clearly called out in patch notes, so you’ll always know when something directly related to save stability has been addressed. This approach lets the team focus on durable fixes while still keeping communication clear and at a regular cadence.

Here’s the list of the top community concerns we’re investigating for our next update:

• [EA Forums] Resolved an issue that caused photos to turn black discovered after the January 13th Base Game update.
• [EA Forums] Fixed a UI issue in Create a Sim that was preventing elements from displaying in turn ons and turn offs, as well as the like and dislike buttons.
