Luckily I was in a store with an older more experienced tech looking over my shoulder who told me no, that's just the way Wurly pins 'em! As they age the wood between the pins breaks out because the pins are so close together in the center octaves and they use a long(2&1/2")pin which gives more chance of it moving around in the wood more. I have replaced the broken screws with lag bolts after first cutting a screwdriver slot in the head with a dremel tool so I don't have to carry a socket for them. I just had one last fall with sluggish whippens & jacks, I treated them with 50/50 alcohol/water and hit them the next morning with my blow dryer. I took the action back the next day and I only had a couple I had to treat a second time.
