So, my sim, Kylen, and his Husband were at the Karaoke Bar during the Geek Con Festival. During the Festival, the game would only let one of them sing a duet with the bartender... It took tons of in game hours before they could sing a duet...
I kinda feel bad for the Bartender Townie though. People are playing video games, launching rockets, and my twin with no programming skills won the hackathon contest just outside. Like, it was my Creative twin that I specifically developed Creative skills with. It would have made more sense if my Genius Twin won...
Edit: Anyways, my point is that the game does have a weird way of rigging certain interactions, and my Legacy Heir couldn't even do his homework with his teen friends. He sat down to do homework with them, but they just stood around as if they didn't have their own homework to do. I know they have homework because they are from played households in my rotation... I know they don't do their homework while I'm not playing the household. They are merboys, so I know they are visiting the beach and swimming in the ocean when they should be at school too!
