Well to be fair, one has found them. In parallel to doing damage control as mention before i would certainly contact the party and friendly invite them to share more information in exchange for a token of good faith (discount or a gadget). If you feel good about it, offer a job with reward to fix it. If unsure about how much a reward should be, keep in mind how expensive it could get without.. often a costly chain-reaction of disasters.
