...when trying to buy a house plot, just let us pick a number 1 - ???. Take the amount of gil that is required to buy as a deposit from anyone who bids. Leave the plot open for a certain time period (maybe right up until the next devaluation?), and give the plot to the person who was closest. Refund everyone who doesn't get it. That would at least save us from sitting in front of the placard for hours spamming.
After 7 hours spamming at the same lot, I'm about to lose my chance at it simply because I need to go to sleep for work tomorrow.
