Will the July 21 Update Affect Mods?

I play The Sims 4 on PC through Steam + EA App, and I wanted to share some info for anyone worried about the July 21 update.

Yes — this update will affect mods. It changes core systems like saving, memory management, autonomy, and routing, so script mods will definitely need updates. This is normal for major patches, especially ones that touch deep parts of the game.

If you use mods, the safest approach is:

• Turn off mods before updating
• Delete localthumbcache.package
• Wait for mod creators to update their files
• Redownload updated versions
• Test your saves after everything is updated

Memory Boost doesn’t interact with GPU voltage or power limits, so it can’t damage graphics cards or consoles. It only improves RAM usage. Modern hardware has built‑in thermal protection, and console patches must pass strict certification from Sony/Microsoft before release.

So yes — mod users should prepare, but the update itself is safe. Just follow normal patch‑day steps and wait for creators to update their mods.
