Sims can't sit on chairs or sofas (mod related problem) after update.

Question

Hi! I'm experiencing problem after February 3, 2026 update, where my sims can't sit on the chairs or sofas, only on beds and bar chairs. My Last Exception is telling me (AttributeError: 'NoneType' object has no attribute 'expected_kwargs') and last exception assistant tells me "outdated tunable resource error and outdated tunable resource (interaction) requires removing" how I can find the mod causing this, I have tested probably all my biggest mods and have updated most of them aswell and also tested some smaller mods, but the problem is still there.
&nbsp;
(All of these are tested one by one or updated and are not causing the problem.)

Hi, thank you, but I finally found the problem, it was llazyneiph_rm.ts4scrip that was accidentally left behind after deleting Royalty Mod some time ago! I appreciate all the help! :)

Please test completely mod/CC free. See the instructions for vanilla testing in How to Use Mods and CC
Please note that some mods that commonly cause this sort of issue cannot be named in these forums due to changing the game rating, which is for 13-year-olds up.&nbsp;

I have tested without mods/cc and then the sitting was working.

Jusu12345​ You can check the Broken and Updated Mods and CC thread, but if you use 18+ mods, you'll need to check with their creators for information.&nbsp;
Instructions on how to narrow down a broken mod are in How to Use Mods and CC
