Hi there,
I am not sure if you have solved the problem yet but I had this problem and was able to fix it. I removed my saves from the game and copied them into a different folder. I then repaired the game, opened it without the saves. After closing the game I moved my saves back. When I reopened my world, I noticed that the lot I was playing on was residential even though when I downloaded it from the gallery I made sure the lot was a Haunted House Residential, so I changed it and then Guidry turned up two days after and the Helping Hand became responsive. I am not sure which of the things I did fixed it but you can give it a try.
Hope this helps if the problem is not resolved!
