Not able to do the "dance together" interaction.

[Laurencius]

Since I loaded Late Night my sims have not been able to "dance together" with any other sim at all. Neither at home nor in the clubs. They can "call over to dance," but not actually dance together.

Anyone else with this issue? Is this a working-as-intended sort of thing?

My Dynasty family in Sunset Valley are still able to dance together, no change.  Have you tried exiting your game and reloading?  Sometimes things like that are just a temporary glitch that goes away when you restart the game.
