What happened to the trick-or-treating?

I have noticed that the characters now walk on the grass between buildings and houses instead of just staying on the roads, a slight annoyance cuase when I try to tap them to assign a task, those slippery devils evade me by ducking between buildings and I click on the building and accidently speed up a 5 minute income task and waste 2 donuts, worlds are colliding!! (clearly not to that extreme, I am a TSTO addict.....)
