Apparently, Sierra is very popular...

Do you have the MCCC mod by any chance and have a story progression on through that mod? If not I don't understand why she keeps getting married because she shouldn't unless neighborhood stories are on in some way. Is she moving out of her lot or is her SO moving in with her? Because if she is unplayed she shouldn't loose her job even though her marital status changes, or get another job one unless the neighborhood stories are on. At least that has not been my experience...

And I just read your msg again and it's the marriage you are bothered by not her change of job, which as I understand your post, she does keep despite her marital status :neutral: But as I said, the game shouldn't keep giving her away unless some story progression is on.
