I play rotationally and some of my sim couples randomly aren't married anymore, the relationship status also seems glitched. I don't use any mods and never have. It seems to have started since the last update because I didn't have this problem before. I play with neighborhood stories on but this has never happened before the update.
This is happening to my game recently, even without Neighborhood Stories. I go back to a household and the couple has divorced, even though they are still living together and have full Romance and Friendship bars. It's weird.
I have this issue as well. All of my married sims when I stop playing that lot they end up divorced. I turned off automatic romantic relationships and it still happens. I don't use mods either.
The same thing was happening to me. I ended up turning neighborhood stories off. So far, so good.
