Interaction Bugged: Only Gift & Group Story Options Available

Mods or CC: Yes (about 3GB of mods)

Game Version: 1.113, updated to the "Careers and Hobbies" DLC (not the newest 1.115 yet)

Hi everyone, I'm running into a frustrating issue with one of my Sims (let’s call him Sim A), and I’m really hoping someone here might be able to help.

Everything was going fine in my game until I noticed that Sim A suddenly could not be interacted with by other Sims. From the screenshot you can see that Sim A can still perform social interactions normally when he interacts with others, but when other Sims try to interact with Sim A they can only give gifts or tell group stories. Everything except gift and story  is missing. On top of that, Sim A cannot be selected as a party guest or host.

Here’s everything I’ve already tried (and I clear local cache and reset sim every time):

- Renaming the Mods folder → bug persists  - Moving Sim A to a new household → no effect  
- Renaming the Documents > The Sims 4 folder → bug disappears in a brand new save, but Sim A saved from the bugged save is still glitched  
- Using Sims 4 Studio for batch fixes  
- Using Resaver (4 attempts, no fix)  
- 50/50 method with mods.  Finally, every mod out, still the same bug.

Sim A’s traits and behavior seem totally normal. The only unique thing is that he previously had some skills from a gameplay mod （Basemental）that adds custom interactions (now removed), but even after removing it completely, the bug persists.

Has anyone encountered something similar or found a workaround for Sims that become “unselectable” by other Sims for social interactions? Thank you for any advice!
