Sim only creates "poor" quality things regardless of skill level
Hi!
I have one specific sim that can only seem to create poor quality things. Whether it be food, art, drinks, or even when it comes to his performance in game tournaments he will always lose despite his skill level being 10. It wasn't always like this, he used to be able to create things of different qualities, but now it seems he can't and I have no clue what happened. I don't have this problem with any other sim in the same save, not even his partner.
The only exception to the poor quality is that at random moments he will paint something that is a masterpiece, but it seems to be completely random. His painting skill level is 10.
This happens with or without mods, so it seems to be something within the sim itself. I can't remember if this started happening before he moved to the Fountainview Penthouse in San Myshuno, but my first memories of this is when he just moved there.
It's a legacy save so I'd rather not just paste a doppelganger to replace him or delete him in any way. Is there anything I can do?
