Neighborhood Stories stopped telling me who is in a relationship.

I get the same issue. Ever since the bug about breakups was fixed (thank you for that!), new dating messages never pop up. Just break ups, getting back together, but no new relationships. It doesn't matter if it's on an old save or a brand new save. They're simply gone. I play on long lifespans, so I've made sure there's been plenty of time for people to get together. And the answer is, no. Nobody gets together unless I force it. Which I'd rather not have to micromanage for the entire save 😅
