This could be due to not following naming conventions in the preset you put together. Normally, its author:name, but in your preset, there is no author with the 'PubThick' item. I remember that there are some very old legacy items (clothing) by MeshedVR which also follow different naming conventions. Not sure how to fix this.SIM problem: The previous error problem has been eliminated. There is a problem with the function of automatically canceling the pubic hair sim. It will not automatically uncheck the sim (this problem has always existed). I haven't done much testing, but when I did, it failed. I think SIM is not a high-priority issue. We will study and test it after we solve the problem of hiding pubic hair.
