I know Kevin personally, he and I purchased WOZLE the day pre-orders opened. I'm talking within the first hour of the preorders being open. I'm not shocked by the numbering issue at all. When I ordered mine, I opted for number 50 and put down my deposit. At least I thought I was getting #50 and was not told otherwise at that time.

In March of 2011, someone started a thread on what number you had for WOZLE and I posted my number up (on rgp I believe). Soon after I received a personal email from Jack stating that #50 was given to someone else. He then offered me #29, which I accepted.

I expect they were not tracking the numbers closely (or reliably) at least at the beginning. Thus, in my case two people had the same number. I expect what happened with me happened with Kevin and the OP as well.
