Failure: '__init__' () Empty module name

Over the past two days, I’ve received a flood of identical support requests about one frustrating and misleading startup error. After thorough testing, I’ve confirmed that the issue is caused by Royalty Mod version 3.5.2 — not by any of my own mods.

If you're seeing an error on game startup that blames one of my mods (such as Object Tuning Replacement, Smart Core Script, Trait Tracker Injector, Injection Tools, etc.) — please do not message me assuming the issue is on my end.

This error is caused by how the Sims 4 engine handles broken script mods. If one mod fails to load, the game often blames the first script in the list, even if that script is working perfectly fine. This is misleading and results in many false reports.

📌 What’s actually happening:

On startup, the game throws an error like:

• Failure: '__init__' () Empty module name (ValueError: Empty module name)

This means that one of the loaded mods is trying to register a module with an empty or invalid name. When this happens, all script mods stop loading, even if only one is faulty.

💡 What you should do:

• Remove all mods except Royalty Mod, and start a brand-new clean save.
  ⟶ If the error still appears, this confirms the problem is inside Royalty Mod.

• Please don’t report errors to other creators unless you’ve done this kind of testing. False reports waste everyone’s time.

• I’ve already opened a support thread on llazyneiph’s Discord server.
  If you’ve experienced this issue, please reproduce the error as described above and add your confirmation in the thread. The more users confirm it, the higher the chances the issue will be addressed quickly.

My mods have been thoroughly tested and do not cause this error. Please don’t open support tickets for this unless you have concrete proof that the issue is coming from my code.

Thank you for understanding and for your support!
