Yes, I am having the same issue as well! When I played yesterday, my ghost sim did chores and helped my sim's household "clean up." But I didn't really make my sim clean up before doing the "Skillful sleep." I think I made my sim mop one time and then go to bed to take the "Skillful Sleep," but then my ghost version of my sim just continued to clean up, which is a new activity that my ghost sim self does, and they appear to still be around even after my sim wakes up. I can't interact with my ghost sim self, and I can only hover over them, and they will show me the details of their name but won't have the "Skillful Sleep Sim" info alongside with the ghost version (because apparently, they're supposed to tell you that it's a "Skillful Sleep Sim"). But I still can't click on the ghost version of my sim. This is a new activity that the ghost version of my sim does, but I bet you if I had my sim eat and then go take a Skillful Sleep; that ghost version of my sim would just eat. I've seen this working for some other simmers, but it's just not working for me. I don't know if it is mod related (I feel like it shouldn't be because my Sim doesn't wear anything that's CC or mod related). I do have mods in the game, but that's because I feel like the game is more fun to play with, with mods installed. I'd be a little upset if I had to uninstall my mods and not re-install them. Every time the game has a new update, I just move my mods over to a backup save folder, and then "re-install" them by moving them back into my mods folder.
