I'm plot resetting to get my villager to move in this exact spot. Is it even possible for said villager to plot their house here? Just double checking so I won't spend extra time plot resetting.. https://imgur.com/a/XC7UHkV
It's hard to tell because of this small distance to the cliff. I would say try it out a few times and if the
house doesn't show up on that spot then I guess it will not work. After all, an (villager) house needs
enough space around it if it's next to a cliff, river, pond, rock or another house.
Very likely, yes. I’ve had villagers in similar arrangements, and it looks like the one corner by the cliff can hold a pattern tile, so it should be safe.
