I have good news and bad news, I believe this was a wicked whims bug which broke the simology tab, Better Exceptions flags it as a UI Cheat Bug for reasons I don't know, the good news is if you updated your wicked whims recently the bug won't happen again on new sims, the bad news is I don't know of a way to fix sims already affected by it and you might just have to write them off as borked, it happened to me recently till I realised it was the sim that was faulty and not anything else, to check if a sim is affected just click on the Simology tab and your UI will bugout completely making it so you cannot access anything including the options menu at that point considered that sim DOA.
