I just bought a Haunted House. Many plastics are broken. As I play it seems the ball bounces a lot. I was going to buy new plastics... but now I am worried they will just get broken as well. Am I correct that plastics are just naturally in danger on this game? Is there anything that can be done to protect the new ones I put on? Sucky that they only come as a set. Are there certain plastics that are always breaking on Haunted Houses? I would like to hear from owners of this game. Thx!
