So I decided to place some lots in Moonlight Falls before I started. One of them was Twinbrook's laundromat, since I'm pretty sure there isn't a laundromat in the lot bin (and I really want public laundry!).
Now, Twinbrook's laundromat has a grave on its property. Somehow, I can sense there being some sort of rule broken (or at least some grey area) in this grave, especially if there is still a Twinbrook ghost attached to it. It strikes me as almost breaking some rule about not placing any other sims other than your founder (especially since this is the Life States Dynasty, and that ghost could be of benefit to someone).
I wouldn't use the ghost in my dynasty anyways, and hope that I can pretty much ignore her, but this is bothering me now.
