RNG Fairness

[Evergrey]

There's a different set of problems with that though.

Your scenario doesn't have people who transferred their lot to a new plot to factor into whatever solution they come up with.

Your analogy is flawed.

If they can't rollback JUST the housing districts to a point after the bidding closed and before the winner drawn, then there is no perfect solution. Those who won a lot should keep them, the sole bidders should be given their plots, and the bidding reopened once they've fixed the bug.

roll back all housing wards to the point before then.
Then it would be as if nothing had happened and things were as they were before this problem happened.

Easier said than done perhaps, I know.
