Time will tell! You didn't do them any good! Did the shop look over the limbs and cams? Take a cotton ball and rub all over the limbs, if the cotton snags anywhere = not good. More than likely a split has started. The cams can be bent, just use a straight edge in every direction. I can probably guess what bow it is, but why not tell us the bow. One of the bows that have had this happen a lot, (derail), has a new design on the cams, one with deeper grooves.
