Muscle tone not properly displaying in CAS and live mode
I've been playing The Sims 4 on PC for 10 years, and I have encountered with this bug 8 days ago for the first time ever.
When I upload my Sim to Gallery directly from live mode, her muscles are showing properly in CAS. Her muscles slider is up to maximum, and her weight slider is down to minimum, she's been very active in the gym. But, when I pick up her muscles slider and "move" it up, her muscles shrink and now appear like half the size.
But in live mode, when I save her in CAS and start a new game, in both cases, her muscles appear the same - from a distance, they appear normal - but from close up, the muscles are gone, and she appears like having no muscles.
I have reset The Sims 4 folder, I have repaired the game, I have deleted all cache, I've got no mods nor cc.
