I still... for the life of me... can't get any Autonomous situations to occur. The only mods I have are animation mods, body mods, item mods for animations, clothing and hairstyle mods, and DD.
DD and its required mods are the only ones that have .scripts so its not like there's anything competing with them.
I go to a public place, turn down the arousal minimum, put my sim on an activity, and just wait... for hours in game... and nothing. Sims come and go, their arousal goes up, they walk around, stop and give me tips for my guitar playing or whatever, talk to each other, and still nothing.
