UPDATE:
I just started a new save file with no buildbuy or CAS cc and it worked just fine as normal no weird idling.
and then I just started another new savefile with CAS cc and no buildbuy items and I'm still getting the excessive idling -> so it seems to be somewhat linked to CAS cc conflicts. Though nothing is showing broken from my sims cc CAS outfits. I copied 1 outfits through out all 5 outfits and I'm still getting idling (non broken CAS CC)
[additional note] i noticed it takes their needs going into yellow for them to move autonomously - and every time they blink the idle animation resets.
