For those still having the problem, when you go to click on the platform, is there a wardrobe sim standing next to it?
If not, that's why the option isn't there.
There are several reasons they didn't show up. I believe that job is assigned when you initially take the gig. If that sim dies for some reason between the time you took the gig and when you actually showed up, they will not be replaced and it won't work.
Also, most mods that claim to handle "npc spawning" will break that. Mods like NPCC will break it every time. NPCC should NEVER be used.
The best way to handle it is to remove ALL mods that claim to control NPC spawning like NPCC, then finish or quit that gig and take another.
