Should You Update The Sims 4 Before Updating Mods? It’s one of the biggest questions players ask before every major patch, and with the July 21 update introducing AutoSave, Save Reminders and Memory Boost, many players are wondering whether they should install the update immediately or wait for their favourite mods to catch up.
If you play The Sims 4 without mods, updating as soon as the patch becomes available is usually the best option. However, if your game relies on script mods or a large custom content library, waiting a little longer could save you hours of troubleshooting.
Should You Update The Sims 4 Before Updating Mods?
Whether you should update depends entirely on how heavily modded your game is.
If you use mods such as MC Command Center, UI Cheats Extension, TOOL, Better BuildBuy, Wonderful Whims or other script-based mods, there is always a chance they will stop working after a major game update.
While many creators release compatibility updates quickly, some may take several hours or even a few days to test their mods against the latest version of The Sims 4.
For players with long-running saves, patience is often the safest option.
Why Should You Update The Sims 4 Before Updating Mods Carefully?
Every major Sims 4 update changes game files.
When those files change, mods that rely on them can experience problems ranging from small interface glitches to complete failures that prevent gameplay features from working correctly.
Possible issues include:
| Possible Issue | What Can Happen |
|---|---|
| Broken UI | Menus fail to display correctly or disappear completely. |
| Script Errors | Error messages appear when loading a save. |
| Missing Interactions | Sims lose options or gameplay features. |
| Custom Content Issues | Some CAS or Build/Buy items may not work correctly. |
| Save Problems | Loading heavily modded saves immediately after updating can increase the risk of issues. |
This doesn’t mean every mod will break, but it’s impossible to know exactly which ones are affected until creators have tested them.
What Should You Do Before Updating The Sims 4?
Before installing the latest patch, it’s worth taking a few simple precautions.
Back up your save files
Copy your saves somewhere safe before updating. If anything goes wrong, you’ll be able to restore your progress.
Back up your Mods folder
Creating a copy of your Mods folder means you can restore everything if you accidentally delete files while troubleshooting.
Wait for compatibility confirmations
Many mod creators announce whether their mods are:
- Working
- Under investigation
- Broken
- Updated
Checking these announcements before opening your favourite save is one of the easiest ways to avoid problems.
Should You Update The Sims 4 Before Updating Mods If You Don’t Use Mods?
Yes.
If you play an unmodded version of The Sims 4, there is generally very little reason to delay updating.
The July 21 update introduces several useful quality-of-life improvements, including AutoSave, Save Reminders and Memory Boost, along with a range of bug fixes designed to improve stability.
Installing the update lets you take advantage of those improvements immediately.
What Happens If You Already Updated Before Updating Mods?
If you’ve already installed the patch, don’t panic.
The first thing to do is launch the game without your Mods folder installed.
If the game runs correctly, you can then begin adding your mods back in once creators confirm they are compatible with the latest version.
Avoid loading your most important save until you’ve checked that your essential mods have been updated.
Which Players Should Wait Before Updating?
You should strongly consider waiting if you:
- Play with dozens or hundreds of mods.
- Use script-heavy gameplay mods.
- Have legacy saves you’ve spent hundreds of hours building.
- Don’t want to spend time troubleshooting immediately after the update.
Waiting 24 to 48 hours gives creators time to test and release updates, making the transition much smoother.

Should You Update The Sims 4 Before Updating Mods? For players without mods, updating straight away is usually the best choice.
