NPC Sims don't show up?

I noticed this while playing one of my families who live on the Sporting Space lot in Brindleton Bay, the sims get stuck where they spawn in to walk to your sims' abode. 

I saw the sim and tried to have my sim interact with the person that asked to come over, and they had pathing issues. (I did a right-click reset sim and they were able to move just fine.)

I'll try to get this to happen again to post screen shots 🙂

Edit: Screenshot. (It always happens in this area, they either have pathing/routing issues or they just don't move from it.)
