SE,

You have the ability to give the people who rightfully won the lottery their house. Do so and make them pay for it again.

Do not raise your hands, hotfix the generator, and make everyone go through the lottery again. Many people and FCs were the only participants for their plot and lost. This is an issue of your creation, many, many, many of us have waited for years for a chance to get a house only to have what would be a guaranteed, legitimate, win taken from us.

If a player or FC were the only ones to bid on the plot and lost it to the bug, guarantee that they can purchase that plot.

If multiple players were bidding on a plot, re-run the number generator with ONLY THOSE PLAYERS who participated in the first run.

DO NOT make a quick fix to the generator system and make everyone go through the lottery again.
