That’s interesting. I wonder if this was intentional on their part (if so, strange), but even if it wasn’t that probably explains the glitched plot phenomenon that’s been going on.
I would assume yes. I don’t see any reason why using a Dodo Code should be any different.
What I’m wondering is, because of the way you have to have a plot down before a villager can even move in, if you have no plots available will they still show up from the void?
