No kids showing up for Trick or Treating?

I didn't expect them to walk in either and I had to stop them, greet them, and then I got the option to trick or treat. I don't think them walking in and getting the candy counts towards the holiday goals since with the first kid the green check didn't start to blink until I chose treat (or trick for one of the other kids). But it shouldn't be that convoluted, they should knock and then we should get the option to trick or treat at the door. Maybe they'll change this in the next update.
