what hapens if you hoave the same mods twice in sims 4

If you have the same mod twice in Sims 4, usually the game just reads two copies of the same file, so the main downside is clutter and possible confusion when you’re troubleshooting. But if one copy is older or slightly different, it can cause conflicts, errors, or even prevent the game from loading properly.

What can happen

• Nothing obvious, if the files are truly identical.
• Slower troubleshooting, because it’s harder to tell which file is causing problems.
• Errors or broken behavior, especially if the “duplicate” is actually an outdated version of the same mod.

• In some cases, duplicate or conflicting CC/mods can stop the game from loading at all.

Best practice

• Keep only one copy of each mod.
• Remove duplicates and delete the localthumbcache file after changing your Mods folder.

• If the game acts weird, test with mods removed and add them back in small batches to find the problem file.

Simple rule

If it’s the exact same file, it’s mostly wasted space. If it’s two versions of the same mod, that’s where problems usually start.
