Props permanently disappear from Showtime stage venues after first performance by any Sim.

What is the lot tag? What does the game consider the lot to be? That’s pretty much what the lot designation is. You can change it in edit town. If you set the lot something like a sports bar, ( one that came with Late Night ) magicians, singers, and acrobats, will be scheduled to perform there at times when the lot is closed, on the other hand if you set it to say an exclusive club ( something that came with Showtime ), that won’t be an issue. You can’t reschedule performances without mods, unfortunately.
