The good news is that since the 22 August 2017 patch, the Flea Market vendor tables seem to be working again and vendor sims can sell things again.
I also spotted my comedian Randall (who the game picked to be a vendor while I had switched to playing Penny Pizzazz) trying to sell his comedy routines again, so I managed to get a screenshot of it actually happening as proof.
This time, after I watched him clear the table and walk home, I switched characters to check on him. The routines that I had saw on the table are now missing - they aren't available for refining on the computer or for performance on the microphone. They also aren't in the household inventory this time. I don't know if they are now permanently missing or if they will eventually reappear after a few days.
I hope this gets fixed. I didn't mind before when they reappeared, but this time I don't know if the changes they made to the table make the contents vaporize completely after the tables are cleared. I didn't see the green dragon toy or future cube that were on the table anywhere in his inventory afterwards either.
In an experimental save, I had Penny buy one of the comedy routines. It appeared in her household inventory when she returned to her apartment, but it was unusable, because when I moved it into the world it just disappeared this time instead of being able to be placed on a table and be picked up.
Thanks for the follow up
