Now I am astonished at this, but is it a coincidence?
Let's think about this, would blizzard really think that people would figure this out?
I mean yes you seemed to have figured it out, but at what point did they say "Hey, let's make an error message out of hexidecimals that fill our evil scheme"
It's very interesting, and very factual, but in basic theory, WHY would they do it and HOW did they know someone would figure it out?
