Duchessducky, your error with the maid sounds familiar to a game issue Deaderpool discusses in her forum. She looked into the issue and found a ghost sim without a household. It was causing several game issues, and she created a fix for it. I hope this comment doesn't get me banned for discussing a mod, but it'll clean those malfunctioning sims from your game. In her example the game cycles through all the inactive sims to find matches for clubs, but the same function would happen when the game cycles through looking for a maid or any other inactive to fill a needed role.

Quote "Ok, so here's the deal. It is something that EA could code around, but it is also data-specific. In your world, you have one Sim, Lucas Munch, who is from what I can tell, corrupted. He is a ghost, but he has no household. Normally ANY Sim has a household. If they're ghosts, they usually have hidden households but they still have households. Lucas does not so when the core scripts are iterating through all Sims to try to find replacement club members and they're running tests on each Sim, when the test gets to Lucas, it gets that error because he has no household and he should.
I have put together a fix for this bug, but if you actually have a corrupt Sim, it could generate other errors in other places. That I can't say. I just don't know how common this is so I don't know if EA should apply a fix for the issue or not. There's really not much else you can do about the corrupted Sim other than delete them and you'd lose some of the Pancake family tree if you did that.
Also, I don't know if the club causing the bug is a club you made or a club that came with Get Together. The particular club criteria that blows-up is a wealth-type limit on the club that a Sim must be "Rich" to be allowed in the club."
She is referring to that club that auto-generates, I forget the name. It's for people with 30k+ who are tired of being looked down upon when they discuss needing to add a new wing to their home, and other problems of the wealthy.
