You can't even code a simple random number picker correctly.

I have to wonder if the numbers were all shifted by 1. Meaning that if 0 was a possible win, was the very last lottery entrant excluded completely (hence why people who had ticket #1 lost)

There are reports on the reddit thread of people winning with the highest number (i.e. 8 bidders, #8 wins) so it doesn't appear to be a purely off-by-one error. Seems like the whole range was considered plus zero, or something else internal is going on.

The QA & coders are hopefully getting reamed into the ground right now for whatever the underlying issue is considering how significant a feature this was.
And they deserve it. Even if this was their failsafe, it's a pathetically displayed one that serves to confuse and disrupt the players.
