Hah! That's unfortunate, but actually also kind of hilarious. I hate godmodding, but am glad you guys at least had a good canon way to resolve that. Just a shame you needed to.
Gonna start off and make it clear that IDC what you do with your houses, but I still think it's ridiculous that SE designed a housing system so wonky that people can just buy up dozens of houses by making shell FCs or whatever other methods people are using. You and others with the time/money (both gil and cash) to buy up a ton of plots can do as much sub farming and gardening as you want while other people can do exactly zero unless they have a close friend and/or FC leader that they trust.
Not a single house in any ward or subdivision in any housing zone on my server btw. Checked all of them just now. Miserable system. Not a dig at you, to be clear again, but a dig at SE for designing the system like this.
