[OPEN] NPC Sims drop everything to shovel snow piles

I've just noticed this as well.  I have a played sim with the neat trait who shovels all of the snow, but I also saw a bunch of townies shoveling snow at one of the festivals in the Snowy Escape world.  I couldn't get my sims to build a snowman because townies kept shoveling the snow piles.  (Even with the neat trait, however, sims shouldn't be going out in blizzards to shovel snow that's on terrain.)
