Sims won't cook and can't dance

I have a couple of Sims on vacation and they were cooking meals just fine in their vacation home at Three Lakes. But they got back from meeting that hairy guy (forgot what he is called, senior moment) in his burrow and now they won't cook. We were having a good time, did all the tours, got souvenirs, played games, entertained new friends and even have a garden going great guns. They won't check food levels in fridge so I asked for food delivery and they could only order a tiny amount so I figure fridge is full; beside if there were no food I would have gotten a message.

About the dancing: they went to Tikki and would start to join in the hula and everyone else just stopped so my Sims didn't learn the dance. Same with the slapdance at Three Lakes. The dancing I can live without but the no cooking is going to make things a little challenging. One of the Sims in the couple is employed as a celebrity chef. Maybe all this will go away when the get back from vacation.
