If the zero was only added and the count was not shifted by 1 because of it, then there’s absolutely no need to re-roll and the result is fair because the odds were equally lowered for everyone.

For example, if 4 people entered the lottery, each would have had a 25% chance to win, but if they dropped a 5th “zero bidder” into the mix, all it means that now all 4 real people simply had a 20% chance of winning… and there was a 20% chance that the drawing fails and hits the zero. If it didn’t, though then how exactly is it unfair?

Only those cases where zero actually won need to be re-rolled (and the single bidders should just get the house, of course).
