[ARCHVIED] Hired roles don't show up

This is happening to me a lot lately. At weddings or parties, if you try to hire for any role, you pay for it, but the caterer, mixologist, piano player, etc. never shows. If you directly try to hire for the role, they don't show up. So now you've paid for a service twice and no one shows up.

9 times out of 10, the hired roles don't spawn. On the rare times a hired role does show up, it's only when I've directly hired them by clicking on the bar/stove/microphone etc. (as opposed to hiring when planning an event).

But even if they do show, they show up late (when the timed event is nearly over) or leave before an event completes. So you get a caterer or entertainer for maybe a Sim hour or two. Or my personal favorite is when the bartenders don't tend to the bars but instead mingle with all the party guests they're supposed to be serving drinks for, hahaha. So the hired person doesn't even attempt to do their job, they just act like a guest. It's comical but it's also frustrating.

My host Sims have to do the work they hired out for.
