As from Apartment Life, NPCs no longer run the BHAVs on themselves which were cloned from the relevant template! They actually run the BHAVs in situ on the template. That means if you want to change the behaviour of an NPC you only need to make a patch for the template or individual BHAV on the template, and all your nannies or whatever will start using it, without any retrofitting!

Oh that *is* nice! :D

That's almost enough to make me want to get AL... Almost, but not quite...
