Platinum townies? As far as I can tell, they don't gain aspiration and are perma-green. I could be wrong.
Hmm. I used to see platinum townies, but now that you mention it, I haven't seen them since at least Uni, mostly because I've taken to shunning them and not paying much attention to them. Perhaps something was added to permanently suppress them. In that case, avoid townies, they're lousy workers.
Does anyone know if you make them selectable and then make them platinum, if they will hang on to that status? It seems like they don't because they get pissed off and go home if they're hungry or bored. Thanks.
It has very little to do with their state of aspiration, it has to do with their
needs. If they get hungry or tired, they will leave. They don't want to starve, die or pee themselves on your lot. They also don't want to be bored to death.
It's important for you to help your visitors maintain their needs by being a good host. A platinum aspiration will not help you.
Platinum aspiration will get rid of the temperamental moodiness that causes sims to reject actions for no apparently visible cause, but they'll still eventually leave if a motive gets low.
