Have 3 sims dance at same time not working help please

I am also having this issue. Uninstalled and reinstalled game and removed my sims 4 folder from documents so it was 100% fresh install with no mods. Created a new family and hosted a social event "dinner party". Cannot complete any event goals that require multiple sims to be doing something at the same time. x number of sims eating, dancing, listening to music, just shows 0/x. Seems to be a bug introduced with C&D, hopefully this will be patched soon.
