Ever since I got Vampires, I've had this bug where putting a child sim (girl or boy) into the first swatch of the "Twilight Prince" outfit changes things other than the clothing. I took my mods folder out before I patched the game, and I didn't put it back before trying this. I've tried repairing my game, and it also didn't help.

If the issue remains, try starting a fresh new save game and see if it occurs there also.

I just tested in game, and the issue isn’t occurring in my game.
