I do believe there is a law in nature and physics that states if something shows up once there is a chance it can show up again. To me the questions relating to god and the devil and things of that nature... well proof is not it... can it or more importantly did it happen again, what does that mean overall, is there a way or a need to fix it, or is it a possible solution. Sometimes only time will tell. Obviously keen observation is required.
Also is it a created copy or an incidental flaw and repeat, if so is the copy stronger or or weaker or the same.
