I haven't seen that kind of error ever in over 30 years . I guess randomizing those IDs in general works, and you just were the exception of the rule
If I were you i would play lotto (chances to hit the jackpot between 1:5.000.000 and 1:14.000.000) and avoid the next lightning storm (chance of being struck ~1:280.000)
Anyways...glad you got it sorted out.
I bookmarked the link..just in case
