That's exactly what I meant actually. I know that via Sims 4 Studio, you can update sliders, so I thought that maybe this was possible for presets. I have a lot of presets. I have them for almost every part of the body. I have the more presets mod but Zerbu. The presets I have these sims wearing are by Obscurus and Poyoyo.I did check the creator's Patreon and found nothing about an update. I should also say that these sims are heavily modded. They have a lot of CC on them, including eyes. I did play for a bit last night and saw that the presets stick after replacing the presets and placing them back in game. It was inconvenient, but it's worked so far. I did update a slider by Redheadsims for height and used it with these sims. It works, but I thought it could be the culprit. I removed it and deleted the local thumb cache, but still encountered the same issue after restarting the game. I even reinstalled my game and still, I had the same issue.
