Upside-down face plague

The upside-down face disease is a game disease in The Sims Unleashed where the head icons of sims turn upside down, into a woman with dark-hair, red lipstick and gold earrings. This / website can help you if you are experiencing this. Some pet icons (cats and dogs) may turn into a dog icon, an invisible NPC named Tucker. To protect you game from it, go to The Sims folder (wherever you installed it) and go to any UserData and click the Characters folder. Copy and paste the file into a safer place. When this problem occurs, remove the files in the Characters folder and replace it with the safe ones. Files in the characters folder are files of every sim in the game. To know if a sim is infected, you have to know the sim's code. The average amount of data is about 57KB and up. If it changes drastically, then that means it (could) be infected. Other cures recommended are, reinstall your game and delete your downloads.
