Building mode conflicted with travel

Well, I tried to travel with a friend to the Lounge where the piano was available, so I could continue with the creation of music. I could not find it, my bad memory... However, I switched to world mode and visited all the Lounges I had. To my surprise, some of them were marked as incomplete. Ok, I found one stating with the missing instrument. Thus, I placed a piano there. 

Now, returning to my "travel". I selected my played household and the game indeed asked me to select a person to play. I selected the one who was in transit of visiting places with his friend. And I got an error. Nothing helps now, repairing the game didn't work. Restarting game, as was suggested in the message didn't help either.
