The 4 day wait between when plots are sold and when they can be bid on again is way too long when they're all on the same schedule. Why not make it a rolling lottery where every day there are more plots going on the market and some being sold? You can have a certain number of wards on one schedule and other wards on another. I think you could work the scheduling enough so that you have multiple lotteries going off every day. And then when folks lose out on a bid they can put their money on another house.
