Hey Turbo,
Just for the record. I've done additional testing on the Polyamorous trait. It definitely does NOT ignore the Relationship Awareness Switch. I tested this very thoroughly.
Sims behave as they should with the Noncommital trait. And they behave as expected, when the Relationship Awareness Switch is turned off. But as long as they have the polyamorous trait and the relationship awareness switch is on, they will not engage in autonomous sex.
This can be easily tested, over and over, by using the NPC sex cheat, to make an NPC jerk off. A polyamorous sim (provided they're in a relationship already), will only watch, cheer or leave. But the moment the relationship awareness switch is turned off, they'll ask to join.
Right now, as far as I can tell, the Polyamorous trait is behaving EXACTLY as the 'NotJealous' trait used to. No more, no less.
I remember there being a wickedwhims debug command to automatically trigger an autonomous encounter in the cheat console, and then give the percentages. Is that still usable?
